The "Abandonment" Defense to Criminal Attempt, and the Person Who Was Planning to Kill Justice Kavanaugh
The plan to kill Justice Kavanaugh is horrible for many obvious reasons. But the one nonobvious question that might arise, and that I thought I'd address, is this—it appears that the would-be killer likely changed his mind, which is why he was arrested:
On June 8, 2022, at approximately 1:05 a.m., two United States Deputy Marshals saw an individual dressed in black clothing and carrying a backpack and a suitcase, get out of a taxicab that had stopped in front of the Montgomery County, Maryland residence of a current Justice of the United States Supreme Court. The individual looked at the two Deputy U.S. Marshals, who were standing next to their parked vehicle, and then turned to walk down the street.
Shortly thereafter, Montgomery County Emergency Communications Center fielded a call from an individual who identified himself as NICHOLAS JOHN ROSKE. ROSKE informed the call taker that he was having suicidal thoughts and had a firearm in his suitcase. ROSKE also told the call taker he came from California to kill a specific United States Supreme Court Justice. The Montgomery County Police Department officers were dispatched to the location near the Supreme Court Justice's residence where they encountered ROSKE, who was still on the telephone with the Montgomery County Emergency Communications Center. ROSKE was taken into custody without incident and law enforcement officers seized both the backpack and the suitcase that were still in his possession.
Assume, for purposes of this question, that Roske called 911 because had completely and voluntarily changed his mind (rather than because, say, he was worried about getting caught). Does that mean that he's not guilty of the crime of attempt (setting aside the separate question of whether he's guilty of threatening a Justice), under the "abandonment" or "renunciation" defense?
The Model Penal Code, and followed by some state courts and statutes, say that yes, such a defense would be available; here, for instance, is the New Jersey statute, based on the MPC:
When the actor's conduct would otherwise constitute an attempt under subsection a. (2) or (3) of this section, it is an affirmative defense which he must prove by a preponderance of the evidence that he abandoned his effort to commit the crime or otherwise prevented its commission, under circumstances manifesting a complete and voluntary renunciation of his criminal purpose. The establishment of such defense does not, however, affect the liability of an accomplice who did not join in such abandonment or prevention.
But federal law appears to generally say no (though I know of no precedents from the Fourth Circuit, where the case is being prosecuted). U.S. v. Young (8th Cir. 2010) lays it out thus (and see also U.S. v. Tilotta (S.D. Cal. 2022)):
The Model Penal Code lists two considerations for recognizing such a defense [of abandonment] in attempt crimes: (1) "renunciation of criminal purpose tends to negative dangerousness," and (2) "to provide actors with a motive for desisting from their criminal designs, thereby diminishing the risk that the substantive crime will be committed….
[A]ll of our sister circuits that have faced this issue have either held that a defendant cannot abandon a completed attempt or have alluded to such a determination. See U.S. v. Crowley (2d Cir. 2003) (not formally addressing the issue but noting, "[t]he only other circuits that have formally addressed the question have rejected the defense as a matter of federal law"); U.S. v. Shelton (6th Cir. 1994) ("[W]ithdrawal, abandonment and renunciation, however characterized, do not provide a defense to an attempt crime."); U.S. v. Bussey (9th Cir. 1974) ("A voluntary abandonment of an attempt which has proceeded well beyond preparation as here, will not bar a conviction for the attempt."); U.S. v. Wales (10th Cir. 2005) (unpublished) ("[N]either this circuit nor any other circuit to have addressed the issue has held that abandonment or renunciation may constitute a defense to the completed crime of attempt.").
Specifically, in Shelton, the Sixth Circuit rejected the Model Penal Code's approach and held that "withdrawal, abandonment and renunciation, however characterized, do not provide a defense to an attempt crime." The court explained:
… [T]he attempt crime is complete with proof of intent together with acts constituting a substantial step toward commission of the substantive offense. When a defendant withdraws prior to forming the necessary intent or taking a substantial step toward the commission of the offense, the essential elements of the crime cannot be proved. At this point, the question whether a defendant has withdrawn is synonymous with whether he has committed the offense.
[But a]fter a defendant has evidenced the necessary intent and has committed an act constituting a substantial step toward the commission of the offense, he has committed the crime of attempt, and can withdraw only from the commission of the substantive offense.
We are not persuaded that the availability of a withdrawal defense would provide an incentive or motive to desist from the commission of an offense, especially since the success of the defense presupposes a criminal trial at which the issue would be submitted to the jury for decision. A remote chance of acquittal would appear to have an even more remote chance of deterring conduct….
We therefore adopt the Sixth Circuit's approach in Shelton, specifically reject the Model Penal Code approach, and hold that the defense of abandonment is not warranted once a defendant completes the crime of attempt. We acknowledge, that "[a]fter a defendant has evidenced the necessary intent and has committed an act constituting a substantial step toward the commission of the offense, he has committed the crime of attempt, and can withdraw only from the commission of the substantive offense," not the attempt of such offense.
Note also that different states take different views of when something shifts from mere preparation (not a crime) to a punishable "completed attempt"; but the federal courts, as Young note, follow the "substantial step" test: The government must prove that the defendant had the purpose of committing a crime, and that the defendant took a substantial step. Traveling armed to the victim's house, with the intent to commit the crime, would surely qualify as a substantial step. And the attempt is a punishable "completed attempt" even if the defendant didn't take the final step that would have been in his control (such as shooting the gun, even if the shot missed).
UPDATE 6/15/2022: Just for an illustration of what is sufficient (though not necessary) to show a substantial step, see U.S. v. Gonzalez (2d Cir. 2011), a nonprecedential decision, but a good illustration of pretty clearly settled rules:
To be guilty of attempt, a defendant must have (1) intended to commit the crime and (2) "engaged in conduct amounting to a 'substantial step' towards the commission of the crime." A substantial step requires "something more than mere preparation, yet may be less than the last act necessary before the actual commission of the substantive crime."
The trial evidence, including Franco's testimony and the physical evidence obtained at the crime scene, established that at the time they were arrested the defendants (1) intended to rob Media Plaza, (2) were in possession of the tools necessary to do so (including guns, latex gloves, duct tape, and ski masks), and (3) had arrived at the scene of the planned robbery. The evidence also showed that the defendants and their co-conspirators had cased Media Plaza; indeed, by the time the defendants were arrested Gonzalez had exited the car twice to scope out the area. Moreover, Gonzalez had already put on latex gloves, from which the jury could reasonably infer that the robbery was imminent.
Defendants' reconnoitering at the scene of the contemplated crime while in possession of paraphernalia which, under the circumstances, could serve no lawful purpose (including a real firearm, a starter pistol, and ski masks) constitutes a substantial step, and amply corroborates their criminal purpose. Therefore, the evidence was sufficient to convict the defendants of attempted robbery.
Disclosure: I clerked the same year as Brett Kavanaugh, and got to know him and like him then (and we also both clerked for the same circuit judge, Judge Alex Kozinski, though a year apart). Our paths have crossed on occasion after that, always pleasantly, though not very often.

Roske had a firearm in his Roske? Sounds painful.
Whoops, fixed, thanks. (I had somehow deleted the text "suitcase." after "in his.")
A lot Ivy, useless, verbiage, there Eugene, but I could not find a conclusion. We know you are a good research assistant. You do not have to prove it to us.
He armed himself, had defensive clothing, flew a long distance, went to the house at night. He saw 2 armed guards. That is what stopped him, not abandonment. He went to the phone and called 911, stayed until the police arrived. That is more like a confession.
The fact he wanted to kill himself is evidence of mental illness. Now he qualifies for involuntary treatment thanks to the rent seeking Supreme Court, instead of at home at the onset of his disturbance.
They took over psychiatry 50 years ago to give jobs to lawyers. 10 million Deaths of Despair later, all preventable, but for this rent seeking Supreme Court, here we are. Mental illness and rampage murder almost visited the Court. Of course, they protect themselves with several armed guards, so nothing happened to them.
Interesting anecdote about Kavanaugh, Bruh. Can you make yourself far more useful by researching the money costs of the cases you post about? That amount would be highly relevant and a great explanation for the idiocy of your toxic profession.
Eugene, address this point about accomplice liability.

Also time for RuthSentUs to be dealt with. They provided the address.
Or perhaps subconsciously you were thinking of "roscoe" - old slang for a gun
So he had a firearm in his firearm? No, that wouldn't make any more sense.
Inb4 leftists repeat their CNN talking points that it's actually the left's victims who are to blame for the attempted murder.
I saw a tweet yesterday where someone suggested that this person would not long be remembered, because the left would not rise to his defense like the right did Kyle Rittenhouse.
Those leftists really miss their fallen pedos and communist wifebeaters. If they're so determined to keep their pedos and communists alive, they should stop sending them to try to burn and kill people.
Another mute candidate.
Freaking hypothetical leftists are always so bad!
Inb4 Sarcastr0 has digested any CNN talking points to distribute.

§2X1.1(b)(1): If an attempt, decrease by 3 levels, unless the defendant completed all the acts the defendant believed necessary for successful completion of the substantive offense or the circumstances demonstrate that the defendant was about to complete all such acts but for apprehension or interruption by some similar event beyond the defendant's control.

The jury instructions are also relevant. Anyone have a newer link?

The Fourth Circuit doesn't have model instructions. The District of South Carolina's model instruction on attempt is at page 617 of this PDF, and there is a discussion of the abandonment question in the footnote on page 632.

Had he not turned around I'm sure those Democrat marshals would've turned their heads and stood down.

In normal parlance, one would think that an attempt requires something more than turning up and then changing one's mind - actually firing at BK but hitting a keg of beer instead, for example.
SRG, that was my initial reaction, too. I confess that I never practiced criminal law, so my opinion's not worth much, but I was thinking that an "attempt" meant he shot and missed. But the authorities quoted by Prof. V are persuasive that the circumstances described in the post could constitute an attempt if proved. I assume that the circumstances in which the defendant did not carry out his original intention would be relevant in plea bargaining and/or at sentencing.
"Normal parlance" aside, in legal parlance, criminal attempt has three elements:
1. Intent to commit a crime
2. Taking substantial steps in furtherance of said crime
3. Failure to complete the crime.
Let us imagine, he had entered the house with the intent to murder Kavanaugh, and someone in the house shoots and wounds him. He then changes his mind about killing Kavanaugh. I doubt many would believe that "change of mind" should provide a defense.
Of course, one issue is what constitutes "substantial" steps, and I imagine there is much caselaw on the subject. Looking up someone's address? Almost certainly not substantial. Buying a gun? Probably not substantial. Travel across the country and show up armed at someone's door at 1 AM? I think we've entered "substantial" territory.
Agreed.
I think the lesson here is that if you ever do decide to commit a crime, and change your mind after taking some substantial action to accomplish it, your best move is to just go home and not tell anybody.
OTOH, this guy was admittedly suicidal, and I'm betting this gets him treatment for that. So maybe calling it in was a good move in his case?
A lot of people who attempt suicide, and don't succeed, didn't really want to die. They are very unhappy people who want people to notice that they're unhappy. It can be amazingly hard to convince people to believe that you're suicidal depressed, without an actual suicide attempt to persuade them.
So this guy may have achieved his actual desired outcome.
well he was spotted before so he might have gotten spooked and thought this would lighten the punishment.
What we know so far makes for an interesting fact pattern. If I were a worthless sack of crap who does what this guy did . . . if I actually wanted to be caught before committing any violent act, or if I wanted suicide by cop; I'd probably end up doing something very close to what this guy did. Make all the preparations, travel to the location, bring all my weapons and equipment. And then make sure I encounter law enforcement before I actually have to commit violence. If he had confronted those two first marshals, announced his plan, shown his weapons, then I'd be more likely to think, "Death by Cop." Given that he made a point of not doing this, walking away from the Justice's home, calling into 911, telling them his plan, and then surrendering quickly and (to my knowledge) peacefully; it sounds like he consciously or unconsciously wanted to be caught.
Lock this a-hole up. I don't particularly care if he spends the next 10 year in a prison or in a mental institution. But it does sound like he *really* wanted to be caught, and caught before he did any actual killing. (I think the facts so far are clear that he did take *way* more than one "substantial step" towards completing the action.)
Trying to lay the groundwork of the 'he didn't really mean it so that will lighten the backlash on the cause' narrative I see.
Getting stomped into irrelevance by your betters in the culture war for the entirety of your life has left you nothing but a deplorable pile of bruises, grievances, and scars.
It's nice that things work out as they should sometimes.
Amos,
1. Well, on some level at least, this chap clearly did mean it. Enough to bring a weapon into another state and travel to the actual location where K lives. One of the reasons why, earlier, I talked about locking the guy up for a decade.
2. Nah, I'm not at all concerned that this horrific incident will cause any backlash to the pro-choice movement. I doubt that there's a grandmother in Iowa who supports abortion rights only in cases of rape, incest, and to save the life of the mother, who will suddenly say, "The actions of a madman and animal makes me reevaluate my stance on abortion. Wow, I no longer believe a rape victim should have the right to abort the fetus."
Nor do I believe that the 30 year old single woman from Green Bay who has been adamantly pro-choice will become less pro-choice due to this incident. So, who what kind of backlash do you envision? I mean, it's a wet dream for Tucker Carlson and Sean Hannity, of course. But it's not like they could have moved any farther right from their "abortion is an evil and ought to be made illegal" position they already hold.
If there is an actual group of people that you think might be affected by this; can you help the rest of us understand? (I'm perfectly willing to keep an open mind about this. Maybe there's some population I'm overlooking or missing that you've identified and are thinking of.)
Yeah, I ain’t buying. He was fanatical enough to fly across the country and go to the house. Plenty of opportunity for cold feet in there. His cold feet came when he saw the cops, and knew that they saw him. And the taxi he came in on. Probably not a coincidence.
If he gave himself up when it was clear he had been spotted, he could still be convicted despite the availability of an abandonment defense.
The evidence is thin so far, but I see somebody who is crazy but not crazy enough for an insanity defense to work, like the guy who shot up a pizza shop to rescue nonexistent sex slaves from Hillary Clinton.
Reads like attempted suicide, not an assassination.
How was he going to get away, call another cab?
Why, it's almost like this crazy guy didn't have a very good plan!
He actually did plan on committing suicide after the assassination.
The first paragraph implies that because he likely changed his mind, he was arrested. Which then implies that had he not changed his mind, the LEOs would have been quite happy with letting him proceed with his attempt.
I thought the same thing when I saw the story. The marshals didn’t even stop and question a man whose cab, in the middle of the night, let him out in front of the house owned by the justice they were assigned to protect? The Montgomery County PD responded to the scene; did the marshals rouse themselves to make the arrest or did they let local LEOs do the work? What has happened to our federal law enforcement agencies?
Isn't the most economical explanation that nobody knew he was a threat until he turned himself in on the hotline, and they got word to the cops? Remember he never completed that call before the cops showed up to arrest him.
He got out of a cab carrying a suitcase and walked along the sidewalk and made a phone call. That is consistent with a guest arriving late.
Is it possible that this was his intent all along? To try to intimidate the Justices into changing or not issuing the ruling.
" (and we also both clerked for the same circuit judge, Judge Alex Kozinski, though a year apart) "
Did Justice Kavanaugh do the right thing during the investigation that disgraced Judge Kozinski, or did he comply with the conservative code of silence, too?
This would be a good situation for Republican lawmakers to bring up since they're currently very interested in making sure the mental health needs of people are well provided for before they get to the point of planning to do something violent.
What situation? Are you responding to info not in the post about attempt abandonment? Did kid have any prior indicators? Should he have been on a list? Institutionalized? Throwing dead cats at people's houses? Curious, as I haven't read much about circumstances.
"nonobvious question"? That's my first question.... Well, maybe after "Where did he get his Glock 17?", and "Did he pass a background check?", and "How did he transport his weapon across country?", and a couple others about the encounter with the marshals.
Was it that innocuous? Guy gets out of a cab in residential area in front of known target's house with backpack and suitcase, makes eye contact, turns and walks away. No follow up? https://youtu.be/InFUtXdio3U?t=16
Perhaps gentler treatment would be warranted because he turned himself in before breaking in and firing a shot. But the marshals presence was the deterrence. He "attempted" right up until the point that he met resistance, event if the resistance wasn't directly physical. And the journey to that point took substantial deliberate action at each step of the way - money exchanged to buy weapon for sole purpose of murder (assuming not previously owned), background check, cross-country flight, compliance with firearm transport in airlines/airport(?), violation of concealed carry laws in state/town(?), transportation to residence, exiting vehicle at residence, tools in hand.
There's a strong narrative in (so far) a large minority of half the country that thinks there's visibly a two-tier justice system (J6 vs BLM/Antifa treatment/Mattis & Rahman; Hunter's illegal gun ownership and purchase; Pelosi hubby's DUI; Pelosi insider trading; Biden enrichment; Sussman vs. Flynn; Firebombing of pregnancy centers; Trump rhetoric vs. Schumer/Waters/etc; voter fraud; etc). Regardless of whether you disagree, it's a problem that isn't solved by dismissing the complaints or throwing more logs on the fire. Burying this in the media like Hodgkinson, or gentle plea agreements like Mattis & Rahman, aren't going to do this country any favors right now. They need to very loudly and visibly do their best to throw the book at this guy, no less than any J6'er. Here's hoping.
" There's a strong narrative in (so far) a large minority of half the country that thinks there's visibly a two-tier justice system "
If you are referring to the 25-30 percent of Americans (concentrated in can't-keep-up backwaters) who are dumb and delusional enough to be birthers, QAnon kooks, "stolen election" dopes, JFK-in-disguise idiots, virus-flouting fools, etc. . . . why should better Americans care what those hayseeds think? They are gullible, often superstitious, conspiracy theory addicts and culture war casualties.
Awaiting their replacement is the sole sensible course. Trying to reason with superstition, bigotry, and belligerent ignorance is pointless.
You can transport a firearm across country by air. You have to declare it and it flies in locked luggage. A few pounds of ammo as well separated from the firearm. All quite legal.
Well, until your flight gets diverted to New York or New Jersey by weather or mechanical problems, where they then arrest you when you claim your luggage. Because they've actually arranged to be notified when that sort of thing happens.
Is there a Roske defamation suite [sic] waiting in the wings?
While Roske obviously has shit for brains to me that is the least of my concerns.
Others have mentioned obvious things like how did he fly cross country with a firearm? Did TSA screw up or what? As an aside my last trip to Mexico I bought a hand tooled leather cowboy holster and put it in my luggage and got delayed by airport security for it (probably 1/3 the price of one in the US and the US version would likely be machined tooled). While not mentioned here I saw elsewhere he had burglary tools, again something the is against the law for simple possession in some jurisdictions. Not to mention magazines.
Forget the Kavanaugh stuff. Some clown takes a cab to a high class neighborhood in DC, gets out dressed in all black with a backpack and suit case with firearms, mags and ammo inside and wanders around the neighborhood after being spotted by Secret Service agents protecting a SCJ. Hard to see any happy ending to this story.
Also read at his first court appearance he told the judge he was on meds. Which raises the question of how he was able to get a firearm being on meds. While I am a big 2A guy my understanding is the background check form does mention taking meds.
Maybe there should be a question added to the background check form "do you have shit for brains?"
You can fly with a firearm as long as you do so properly, i.e. something like in a gun case, unloaded, and the airline knows about it. Presumably that's how he did it and he was just another flyer traveling with a gun in luggage, to the TSA.
(I seem to recall an indictment or something saying he told the 911 dispatcher the gun was in a zip-tied container or so, as he'd come from the airport, if you want more than mere speculation.)
In fairness, Alito's attempt to rewrite substantive due process was equally inchoate, and look at all the ruckus that it caused. There's an inherent danger in the near approach of bad things.
Mr. D.
OK, let's look at what happened before he got out of the cab.
He had a handgun which he bought. He's from California.
As a California resident, to buy a handgun he had to buy it in California. Thanks to John Hinckley, one can only buy a handgun in one's home state - the transfer has to go through an FFL in one's home state. If your home is in California and your body is presently in Maryland, you cannot legally buy and take possession of a handgun in Maryland.
To get a handgun in California, he had to go through a background check. (The ever-loving background check which is sold to solve all ills of guns getting into the wrong hands.) And paperwork. I believe some registration and/or approval by the state government is required. But, since I don't live in California and have no intention of going there, he exact ins and outs of Cali's gun control maze don't concern me.
And once he bought the gun, because it was California he had to wait ten days to pick it up, the infamous "gun jail" intended (so said the pols passing that law) to prevent suicides and sudden impulse killings and such like.
So, he went out and waited 10 days, during which time he could have renounced his plan, then went and picked up his gun anyway. Continuing the plan.
All that wonderful California gun control that was going to end all gun violence capital-F Failed.
And then he went out and bought a plane ticket. To travel with a gun by air, it had to be in his checked bag and in a locked container. Ammo had to be packed separately. IIRC, to meet TSA requirements he had to declare it to the TSA and possibly the gate attendant.
So, he jumped through all the security hoops.
Then he got on the plane and flew cross-country, picked up his bag, which had his gun and ammo. He may have then violated Maryland law. Maryland has strict gun control (the form you have to fill out to buy one is literally nearly as long as your arm). I am not familiar with the ins and outs of their law when it comes to people walking around with guns in their baggage and not "just passing through". But, I'm willing to bet it's against some part of their law. (I know New Jersey is notorious for arresting, charging and convicting people travelling with firearms who wind up, quite involuntarily, landing at Newark airport when their flight is diverted. I wouldn't put the same past Maryland, particularly when the guy is wandering around and riding in cabs.)
Somewhere along the line he got the knife, crowbar, zip ties, tape, and all the other paraphernalia that was in his bag along with the gun. Did he go to Home Depot after the airport? Or did he bring all that with him from California.
If the latter, yet another capital-F Failure by airport security. You might think a crowbar and carpenters' tools might be enough to twig airport security. If it was, they failed.
OTOH, if he bought all that stuff in Maryland, that's just further planning and preparation work. Shows two things - he's sane enough to plan and buy stuff appropriate for what he was planning to do. And he's carrying through on his plan.
He was carrying through on his plan until the very minute he got out of the cab and saw cops. It was only when he saw cops that he decided it was time to abandon his plan.
There's no renunciation there. He is quite guilty of an attempt, and with weeks of preparation, too.
That level of planning and preparation, only to abandon the plan at a late stage, would undermine an insanity defense, too.
There's an old joke about a car breakdown next to an insane asylum where the inmate ends by saying "I'm crazy, not stupid."
I think he's not legally insane because he seems to be able to tell right from wrong.
The criminal complaint cites 18 USC 115(a)(1)(A). That clause (https://www.law.cornell.edu/uscode/text/18/115) seems to only covers crimes against "member[s] of the immediate family" of various types of federal personnel. The complaint doesn't mention anything about family. The definition of "immediate family member" seems to be in (c)(2). A mathematician would interpret (c)(2)(B) so that an individual is a member of their own immediate family but that reading seems to be a stretch for non-mathematicians. However (a)(1) makes little sense without the mathematician-style reading so I guess lawyers are like mathematicians in this? That is, (a)(1)(A) applies because Justice K is a member of Justice K's immediate family?
Subsection (c)(2) states:
I don't understand why the complaint fails to charge 18 U.S.C. 1114(a), attempt to kill any officer or employee of the United States on account of the performance of official duties.
I bet they only needed one charge to hold him in custody, and it's the prosecutor's turn to pile on the charges. Is interstate travel to violate 18 USC 115 or 1114 a separate crime? Interstate transport of a gun with intent?
Prof. Volokh: Your post omits entirely the governing legal doctrine, which goes like this (per all S.Ct. decisions defining affirmative defenses in federal criminal law, such as entrapment, insanity, and duress): All federal crimes are statutory, and so are substantive defenses to federal crimes. To the extent that defenses are not set forth expressly in any statute, as most are not, it is presumed that Congress intend to include, by implication, those defenses which were generally recognized in American criminal law (and to the extent they were so recognized) at the time of enactment of the statute in question. (The Model Penal Code was a reform proposal, not a restatement, so it is not necessarily a good reference point on this subject.) I have not investigated when section 115 was enacted in substantially its current form. But circuit court decisions that do not apply the formula just outlined are not controlling or persuasive.
I've seen no mention of how this guy flew in a plane from CA to VA with a gun and a knife. That seems kind of important.
No, not really. It's perfectly legal to fly with guns and knives, you just have to put them in the checked baggage, and report the gun.
I mean, do you think people going on hunting trips have to take the bus?
