To my way of thinking nearly all ATF agents should be arrested for violation of 18 USC 242. But I don't expect that to happen for at least another, like, million years or so. But there is one less ATF agent in the field today which has to be a good thing:
A U.S. federal agent has been charged with second-degree murder in the alleged 2008 shooting of his neighbor in the U.S. Virgin Islands.
Justice officials say they arrested Agent William Clark with the Bureau of Alcohol, Tobacco, Firearms and Explosives. He also was charged with involuntary manslaughter and using a dangerous weapon during a violent crime."
The above is from View From NW Idaho, and since it seems to cause ATF types to meditate upon it rather than doing something more deleterious with their time, I tend to favor duplication.
I would suggest that most law enforcement agencies could be divided into two broad categories - true officers of the peace, striving to reduce the amount of strife and misery in the world by utilizing various and sundry laws and mechanisms to separate the predators out of the herd who generally have my respect and support. And the ninnies with badges and guns (that should be deprived of the first and retrained in the second) who focus on offenses of possession, and largely have my contempt.
The ATF, not surprisingly, strikes me as the dregs of enforcement agencies - that outside of their arson and explosive expertise, have little if anything of worth to offer the world, and should likely be reduced to solely those functions.
