What a silly thing to say. He was no "judge, jury or executioner". He didn't shoot anyone. I watched the video and the cop was certainly pissed but the whole time he had his finger off the trigger.
I agree that he should not have been pointing what appears to be a full auto weapon at anyone. That was just dumb as what he said was. It was stupid he was out on the street in the middle of that crowd basically alone in a cluster of people.
The whole situation was badly handled but it sure seems like this guy is in the wrong line of work. Still, he did not "execute" anyone nor did the cop that shot the thug in the first place.
Yeah, because NONE of the other cops ever had to raise their weapons at the crowd. Right ?
