Why is it a lie? The cops were there because the man was carrying a gun and a baby. The danger that he would go for his gun again is logical.
If the baby had died, people would call the cop a coward.
The phrase, “I thought he was going for his gun”, when there is no gun in sight, is a standard excuse for the inexcusable.
SWAT are supposed to be trained NOT to over react in high stress situations.
They are also trained to have both eyes open when using a scope.
The clown with the baby was likely angry and spouting off, and this is what the cop reacted to. If he was making threats and headed back inside, the shot may have been the correct tactical call. It may be tough to defend legally.
