Have you ever shot a gun before? They don’t work that way. A shoulder or leg is a lot smaller of a target then a chest. Real life isn’t like TV where nobody ever misses their shot. When police fire their guns they are shooting to kill. A person injured in the leg can still return fire.
This is really bad reporting. The text under the headline is wrong. He did not plead guilty to “selling the assault rifle that Adam Lanza used” He plead guilty to making a paperwork error involving a completely different customer and transaction.
