Heard a story several years ago, about a Congressman traveling with his family, when his wife thought she heard something hit the rear of there vehicle. The FBI investigated and found what was described as an AR15 round imbedded in the rear of the vehicle. Upon closer examination he was later told that because of some unusual marks on the bullet, that it was fired through a suppresser. I call BS on the FBI. Would a suppresser leave any marks on a bullet? I don't think so!
