Are there cameras inside cop cars?
How they got inside the cop car and a shot was fired makes no sense with the claims of Brown’s accomplice. How the cop had a swollen face that needed medical care also makes no sense with that story. And the lack of blood and bullet holes in Brown’s back doesn’t fit either...
Here's a plausible scenario:
The cop spots a couple of punks walking in the middle of the street and tell them to get on the sidewalk. They then smart-off BIG TIME.
Cop backs up, stops and starts to get out of his car...and the dead guy shoves the door back at him, injures the cop.
Cop fires one and hits, but perp/deadguy is retreating quick. Cop screams "Stop or I'll shoot" , dead guy turns around and put his hands up.
Cop is enraged, say's eff it and shoots anyway.
There's probably several dozen other plausible scenarios. There will need to be SOME physical evidence to back one or more of them.
