i did live in america for about 8 years so i have a better idea, there will always be bad cops in the world like how there will always be racist people, i'm not saying nothing bad has ever happened to anybody, but i also doubt there's 0 reasons for it all to happen, whether its your fault, or somebody elses, or you were at the wrong place at the wrong time or whatever the case may be, that's just how life is. some people might deal with police on a monthly basis and some may never have any real encounter in their entire life, most police never even fire their gun in their entire career.
It's those reasons that I don't like the BLM movement and all that is happening because no matter which angle you look at it from, it's washing blood away with blood, and irrespective of the circumstances of any of the recent killings, they will say a black person died and it's unacceptable and that's it, then they will go around and loot and burn places down, block the streets so that even men of color themselves can't get to work, and finally have incidents like where police are getting randomly shot at in "retaliation", nobody wins this sort of war. Police should be trained better but aren't, but people in life are so fuckin heinous and shitty that it creates more of these messed up situations. It's not polices fault that there's high crime rates in certain cities, people are just scummy, that goes for any crime.
