Further it is my understanding that shot guns are only used by LE when entering a home by force to breach the door with special shotgun rounds. Once inside the use .223 rounds made to leave most of the energy in the victim. Most the the time done at night under cover of darkness with night vision. They can see there target but he can't see them. They train to place good shots on target with innocent people near by. I don't . I use lesser rounds.
