The guy who was pulled over for the plates not matching the vehicle was about to run.
Got it.
He didn't have shoes on.
He didn't brandish a weapon.
The cop had at least one minute and thirty seconds of video of the guy's face, the guy's voice and the guy's buddy still in the car.
How far is that guy going to go?
How long is it going to take to get him ID'd and issue a warrant?
I'm sorry but all of the "there might have been a gun in the car" and "there may have been a kilo of coke" in the car folks aren't thinking this through. The cop, knowing that there is another male in the car, ran after the driver, leaving the other passenger alone. If he thought that these two were a couple of hardened criminals who were running drugs and armed to the teeth, then what the "f" is he doing - running after one, tackling him, wrestling him around on the ground, etc. That cop had zero concerns about the passenger. None. Entirely inconsistent with someone who was thinking "I just stumbled into a seriously dangerous situation."
I missed the part of the story where the car was reported stolen, the plates were reported stolen, the driver was an identified suspect for the commission of some other crime, etc.
The driver wasn't speeding. He wasn't driving erratically. It was 8:15 in the morning.
Every story I've read (and the video doesn't refute it) suggests that the cop - for whatever reason - decided to run the plates of that particular vehicle as it drove by him.
Proportionality.
