Gotta love old Gordon Liddy...

"Now if the Bureau of Alcohol, Tobacco and Firearms comes to disarm you and they are bearing arms, resist them with arms. Go for a head shot; they're going to be wearing bulletproof vests. … They've got a big target on there, ATF. Don't shoot at that, because they've got a vest on underneath that. Head shots, head shots.... Kill the sons of bitches!"
