No, the police don’t drive drunk drivers home and arrange to have their cars parked safely. No, people waiting at Wendy’s or working there do not confront people who fall asleep at the drive thru. Why? Because those people have broken the law (just being in control of a car while intoxicated is illegal) and might become violent.
No, police don’t shoot at the legs or just to wound. Why? Because they really aren’t that good of shots. They shot for the biggest body mass, which is often the chest.
Cops aren’t going to wait for the mental health specialists, or the drunk driver specialist when there is a situation that needs to be handled right then. They aren’t going to council people in a Wendy’s parking lot in the middle of the night. I’m surprised they had the guy move the car but maybe they couldn’t get him out of the car where it was when he first fell asleep.
People running away from cops, especially those who just took a taser, are a danger. Do you know how many cops are shot or killed when they are trying to serve warrants? Not all suspects can just be picked up the next day because the cops have their license and address (and really, do you think all those addresses are current?).
