"Interfering with the Scent"
From State v. Gardiner, decided Wednesday by the Oregon Court of Appeals (Judge Jacqueline Kamins, joined by Judges Douglas Tookey and James Egan):
A woman reported that a man knocked on her door, stabbed her in the face, and ran away. Hillsboro Police Officers and medical and fire department personnel responded to that call. In order to find the assailant, the officers deployed a K-9-unit tracking dog.
Defendant approached the area on foot and began filming. At one point, while defendant was present, a bicyclist rode through the area after being told to wait 30 seconds by an officer. Defendant had some interactions with officers, and each of them told him to stay clear of the "dog track." {According to officer testimony, the police dog is "trained for [tracking] fresh human odor" through footprints or air scent. Each dog track is never "exactly the same" because factors like weather temperature and wind direction affect a track. During a track, the dog-handler's primary focus is to observe the dog's behavior as it searches for scents, while other officers provide cover for the dog-handler.} Defendant was arrested after he disobeyed Edwards' order to leave the area because defendant continued to walk parallel to the dog track, thereby "interfering with the scent" and interfering with the duties of the police officers….
Defendant claimed this "violate[d] his constitutional right to film police activity," but the court disagreed. First, the court applied the Oregon courts' framework for dealing with free speech challenges under Article I, section 8 of the Oregon Constitution:
The analytical framework for assessing Article 1, section 8, constitutional challenges includes three categories. The first category "consists of laws that focus on the content of speech or writing or are written in terms directed to the substance of any opinion or any subject of communication." The second category "consists of laws that focus[ ] on forbidden effects but expressly prohibit[ ] expression used to achieve those effects." Generally, those laws are analyzed for overbreadth. The third category "consists of laws that focus[ ] on forbidden effects, but without referring to expression at all."
The parties agree that ORS 162.247 is a speech-neutral statute that falls under category three …. In order to determine whether a "category three law violates Article I, section 8, as applied to particular conduct, the court must examine [1] how the law was applied to determine whether the application was directed at the content or the expressive nature of an individual's activities, [2] advanced legitimate state interests, and [3] provided ample alternative opportunities to communicate the intended message." …
First, we consider "how the law was applied to determine whether the application was directed at the content or the expressive nature of an individual's activities." Defendant argues that because the officers allowed a bicyclist to ride through the area and yet "disallow[ed] defendant to film, the officers exercised their authority more restrictively against defendant than they did other members of the public." We disagree. Before the bicyclist rode through the area where the dog track was present, the officer ordered the bicyclist to stop and wait 30 seconds; the bicyclist obliged and rode away without any incident. That interaction does not undermine the conclusion that defendant's conduct of walking parallel to the dog track and disobeying orders—as opposed to the expressive activity of filming the police—were the basis of his arrest. Indeed, the officers repeatedly reassured defendant he could film but told him that he needed to avoid the dog track….
Second, we consider whether the application of ORS 162.247 advanced legitimate state interests. Defendant argues that the application of the statute did not advance legitimate state interests because his following the dog track did not hinder any police investigations. We disagree. The state advanced the legitimate interests of enforcing the statute for three reasons, which we find to be appropriate: (1) an armed suspect may have been present in the area; (2) there were public and police officer safety concerns because of that armed suspect; (3) and the situation was not static because there were no defined search boundaries.
Finally, we consider whether defendant was "provided ample alternative opportunities to communicate the intended message." Defendant argues that officers did not provide alternative avenues because they did not "provide him with specific, clear, unambiguous directions on how to" film the police "that were narrowly tailored to their concern." We disagree. On at least two occasions, defendant was told by at least two officers where to stand to avoid interfering with the dog track. Before arresting defendant, an officer told him to remain in a certain spot. Defendant initially listened to the officer but then began walking parallel to the dog track. Defendant was arrested only after the officers provided him alternative opportunities to remain in specific areas to continue filming.
For the same reasons, we conclude that the officers' conduct did not violate the First Amendment….

I'd like to see some evidence that a dog can distinguish between the random human odor of the perp and the random residual odors of other humans who had been in the area recently. While I understand what the police were trying to do, how do they know that there weren't random people walking through the area *before* they arrived? A dog following the scent from an article of clothing is one thing, but for all the cops know, they could be following the scent of the mailman and not the perp.
IANAA but I don't see a lot of probable cause here. Not without some evidence that the dog is also clairvoyant.
Maybe the dog couldn’t, but perhaps it was worth a shot because of the nature of the neighborhood. If the dog led them so someone, all they would need to detain him was a matching description.
I can’t find reporting on original incident online, so who knows?
It strikes me more as they kinda suspect where they will find the perp (homeless encampment) and want the dog to give them probable cause to search there.
OTOH, if this was a random crime, you can kinda suspect that's who did it anyway...
"for all the cops know, they could be following the scent of the mailman and not the perp."
That would be possible - perhaps even likely - if the mailman came to the woman's door in the interval between the stabbing and the police arriving. Statistically speaking, I wonder how likely that is?
If you are ever unfortunate enough to be in the poor woman's shoes, I hope you tell the officers not to use a K9 lest the dog track some random person instead of your assailant.
===========
As an aside on dogs, we had an untrained mutt once. My wife would be outdoors gardening, which involves repeatedly walking past the basement door about 8000 times in the course of the day. When the dog wanted out to go see her, I'd let him out the door. He'd pause for about one second, sniffing, then head off directly toward her, even if she was out of sight. He did this with 100% accuracy, in all weather, regardless of wind direction or speed, whether the trail was an hour old, or there had been 10 trails back and forth in the last ten minutes. It was just uncanny to watch. He was some kind of retriever blend, not a bloodhound or whatever.
Your wife is a known person, the dog recognized her scent.
I've seen dogs recognize the smell of land and cats recognize the smell of salt water.
But this is a random stranger that the dog does NOT know, and doesn't have an article of clothing to compare to. Call me extremely skeptical that this is anything more than the dog responding to the nonverbal cues of the handler and the handler's suspicions.
Remember too that the EMS was in there, along with multiple cops, and the dog is going to ignore all of those scents?
I think if the dog tracked up to one of the EMT folks, the handler would indicate 'wrong one' to the tracker, and the dog would try another scent trail.
Dogs are indeed susceptible to the Clever Hans problem if there handler wants to fudge things (and even if he doesn't). But dogs can, and do, find random stranger perps who are then convicted. Not because the dog followed them, but because the fingerprints on the guy the dog found happen to match the crime scene or whatever. That dogs can do this is hardly news.
"But dogs can, and do, find random stranger perps who are then convicted."
I am equally sure that there are cases where a police K9 finds a random stranger who has nothing to do with the crime being investigated, but the police don't report those.
There is ample evidence out side of LE K9 training that dogs can distinguish individual people (and individual dogs) by scent.
Being able to determine whose sent trail an individual dog is tracking at a particular time is an entirely different matter.
"Being able to determine whose sent trail an individual dog is tracking at a particular time is an entirely different matter."
To translate the problem to one detectable by human senses, imagine it had snowed. When the human tracker gets there, the front yard is a confused mess of footprints from the police, the EMTs, and the perp. But there is one set of footprints leading off into the distance. It might be worth following that set of footprints and chatting with whoever is at the end of it.
If you move the crime scene to Times Square at New Year's, that's a different problem. Or more precisely, the same problem but with a lot worse signal to noise ratio.
What the police wanted the photographer to do was not walk all over the trail of footprints. That seems pretty reasonable.
"What the police wanted the photographer to do was not walk all over the trail of footprints. That seems pretty reasonable."
I would agree with this.
He was walking *parallel to* the dog track, not on it.
We aren't told here how close he actually is to it. But if he's walking parallel to it, he's neither on it nor going to intersect it.
Heck, humans can distinguish individual people by scent, and even track by it. We mostly don't, but that's because we don't bother practicing the use of our noses, not because they lack the acuity.
They don't need probable cause to use the K9 so this is an irrelevant concern. It only becomes relevant if they use it as probable cause evidence for a warrant on a suspect, and even then it would depend on what other evidence they have to support PC
Setting aside the First Amendment argument, this whole "dog track" bit seems hard to credit. Are dogs detecting "tracks" of scent, or intensities of scents that increase as they near their targets?
Unless the wind is blowing towards them from the target, it has to be the former; You can't smell anything when the wind is blowing the scent away, and it doesn't matter how good your nose is.
It can be both.
A person will shed things (dead skin, skin oils, sweat, possibly blood) on to the ground or other objects they touch that carry that person's scent. A dog's sense of smell is strong enough to pick these up.
Scent can also linger in the air, though for how long is dependent on a lot of variables.
Unless they are tracking a suspect in real-time (the dog is minutes at most behind the suspect) the former will be more reliable.
That just stinks!
The issue is whether the plaintiff potentially interfered with a police investigation, not the probability of success.
That was my take as well. I'd add that I assume that there had to be *some* legitimacy to the police procedure, or a judge might toss the case. (eg, the cops following a psychic who was using a divining rod might be entitled to no deference, so a non-complying 3rd party maybe . . . maybe! . . . would be free to ignore a cop's direction to stay away.)
We have laws against tampering with evidence. This seems no different.
Dude can use a better camera and film from farther away.
Not very practically, but, yeah.
The Human Sense of Smell: It’s Stronger than We Think
In reality, humans have extremely good noses. Maybe not quite as good as a bloodhound's, but better than a lot of species. It's just that we're not in the habit of consciously using them.
Your hind brain certainly isn't ignoring them, though.
Humans can also echo locate like bats.
