I wish somebody would point out that the extensive injuries suffered by Congressman Scalise can be attributed largely to the fact that he was shot with a high velocity bullet from an "assault rifle". Although the bullets are a little smaller than most handgun rounds, they travel at incredible speeds and can cause damage to tissue some distance from their actual track. Basic physics tells us that the impact force of a round is a function of it's mass (weight) and the SQUARE of its velocity. Double the velocity and you QUADRUPLE the force. A regular handgun bullet would have caused him a lot of harm, but the AR bullet, and its instability after impact, causes considerably more damage to a much larger area. They were designed for war, not for civilian use - they should be part of the NFA and hard to obtain.
