I'm not saying this to offset or excuse the officer's actions in this case btw:
I'm just wondering if the guy with the dash cam is trolling for cops to do something stupid.
1 - No front number plate
2 - Tinted windows (they're illegal in the US? I had no idea. How/why do people get their windows tinted then?)
3 - If you subscribe to the belief that black people are disproportionately targeted by the US police, his skin colour
The main thing that I find a bit weird though is if someone brake-checked me in as extreme a fashion as the officer did, I'd say there was a 95% chance I would have verbalised some kind of reaction like, "What the f***?". The driver on the other hand seems as cool as a cucumber.
Btw, I'm not asserting that this was his motive, I just found it a little odd and my reasons are not that compelling an argument. Furthermore, if I was him and that was my motive, I'd have someone else in the car (preferably white), to reduce the possibility of things going out of control (ie. an extra witness), because at the end of the day it won't be much consolation that if I was unjustly killed, there's video evidence of it that's likely to be tidied away out of sight.
