There is a thematic inconsistency in this story, which makes me take none of it seriously. Earlier it said: "...was fired at when he cut off the police car near New York's LaGuardia Airport..."
Was it a "terrifying chase" or did he just cut them off and they took umbrage at the perceived slight?
I will assume that even if the car was an unmarked, they had lights that were used during the "terrifying chase". In any case, it sounds like the cops were jacked up on adrenaline after the chase, and the guy they shot reached for something in a bag when ordered to show his hands.
And why would he be reaching for an electric drill? Does that seem odd to anyone else?
That's what it looks like on the surface ~
Then, when they did their stop and squat in front of the guy out on the freeway he'd be distracted ~ which he was ~ then he could be shot easily on some pretext.
This one ain't over!
