You're right, I can't. I can make an educated guess tho, which is what we as humans do.
The cop in the Minnesota case (which was much more egregious IMO with what we know of the facts) was Asian. IDK if he was motivated by "fear of black people".
As Lupe was sort of implying (in either case), maybe he just guessed terribly wrong. Police aren't geniuses, a lot of them are dumb as fukk, and the government grants them the ability to make discretionary decision on whether or not to kill you if you resist them. LIS, maybe the brehs were literally just afraid of black people. Even if that was the case, the police can and do murder people all the time regardless of if they are motivated by racism.
When I contemplated going to law school, I was taught to never talk to the police, under any circumstances, or admit anything to them, or resist because they could murder you. Police pray on the assumption you are ignorant of the law, why run the risk of them gunning you down out of some imagined fear?
