So we should just execute people who attempt to escape now? She only committed petty theft. All he had to do was let go of the car, radio in her car was escaping, a car would have chased her and no doubt caught her.
No deaths, and she'd have been brought to justice.
She already tried to escape twice, from the cop at the shop then at the car, she refused to stop and paid the price of her ignorance and crime.
If she surrendered like she was told to do twice then she would have been brought to justice but instead she tried to flee and turned a stop into a getaway which would have got worse specially with infants in the car and if she willing to forcefully drive away from a cop with a gun in her face to begin with..well who knows what would have happened to those kids present, you think a woman who would run a cop over or drag his body around in any part of the car would not drive her and her kids around a pole trying to get away from your "car chasing her"?.
Personally any mother who takes her infants shoplifting with her is appalling and maybe they'll have a better life now then grow up like their mother.
