“Why treat him as a violent suspect when there was no reason to do so? “
How do you know that? Maybe the vehicle stalled because he hot-wired it poorly. Maybe he mouthed off to the cop. Maybe he wouldn’t produce ID. Maybe he kept putting his hands in his pockets or into his waistband. Maybe he fit a description. Maybe he just wouldn’t stand still, like he was nervous or guilty.
All capital offenses. </sarcasm>
