Hi Guys, I just found this forum and thought I'd contribute a bit. It's legal for any civilian to buy a bulletproof jacket unless you are a convicted felon. Some states are trying to pass laws to only allow military and law enforcement to purchase body armor.
To follow up on the discussion about bulletproof jackets and to actually see a person get shot at point blank with a .308 and a 44 Magnum, wearing second chance body armor, I dug up a link to this video. You'll notice the guy is standing on one foot and doesn't even make a flinch when he gets shot. So the myth of getting thrown down from a gun shot, is a myth.
