You wouldn’t have shot a leftist based on those rules given that leftists never violently tried to go after sleeted officials en masse and get so close to actually reaching them.If we shot ever leftist based on those rules, the death toll would probably be in the tens of thousands.
If a thousand rioters raided the White House and broke through the doors leading to the Oval Office, they would also have been shot.
Tell it to the police in their police station after antifa poured concrete on the exits and tried to set fire to the building, or the federal court houses that were repeatedly attacked, or ICE where the mayor ordered the cops to stand down so that rioters would have a free hand.
I'm up for a more serious approach to rioters. Shoot on sight? YOu want to play that game? THINK IT THOUGH BEFORE YOU ANSWER.
