Gun rights scholar and reason contributor David Kopel has an excellent post at the Volokh Conspiracy detailing future Attorney General Eric Holder's lousy and troubling record on the Second Amendment:
As Deputy Attorney General, Holder was a strong supporter of restrictive gun control. He advocated federal licensing of handgun owners, a three day waiting period on handgun sales, rationing handgun sales to no more than one per month, banning possession of handguns and so-called "assault weapons" (cosmetically incorrect guns) by anyone under age of 21, a gun show restriction bill that would have given the federal government the power to shut down all gun shows, national gun registration, and mandatory prison sentences for trivial offenses (e.g., giving your son an heirloom handgun for Christmas, if he were two weeks shy of his 21st birthday). He also promoted the factoid that "Every day that goes by, about 12, 13 more children in this country die from gun violence"--a statistic is true only if one counts 18-year-old gangsters who shoot each other as "children."(Sources: Holder testimony before House Judiciary Committee, Subcommitee on Crime, May 27,1999; Holder Weekly Briefing, May 20, 2000. One of the bills that Holder endorsed is detailed in my 1999 Issue Paper "Unfair and Unconstitutional.")
After 9/11, he penned a Washington Post op-ed, "Keeping Guns Away From Terrorists" arguing that a new law should give "the Bureau of Alcohol, Tobacco and Firearms a record of every firearm sale." He also stated that prospective gun buyers should be checked against the secret "watch lists" compiled by various government entities. (In an Issue Paper on the watch list proposal, I quote a FBI spokesman stating that there is no cause to deny gun ownership to someone simply because she is on the FBI list.)
After the D.C. Circuit Court of Appeals ruled that the D.C. handgun ban and self-defense ban were unconstitutional in 2007, Holder complained that the decision "opens the door to more people having more access to guns and putting guns on the streets."
