I wholeheartedly agree with EVERYTHING you said, and thought you explained it beautifully.
I don't disagree with you at all, but honestly I DO think it's hard for white people (myself included) to really understand. Perspective is reality for people, and the thing about perspective is that it all about your vantage point. We all live in the same world, but we experience it very differently.
I remember watching a Dave Chappelle comedy routine where he commented about how differently his white friend felt about randomly taking to a police officer then he did... Chappelle thought his white friend was crazy for doing that, part of what made the joke funny was the stark contrast of how differently the two felt about police in general, showing that perspective is a motherfucker. These types of incidences of police ******* and violence against black men needs to be addressed at the highest and lowest levels, I cannot understand why all police officers aren't required to wear body cams, or why nobody is even pushing legislation for this?!
Over the last several years, with the proliferation of cell phones with video, for the very first time white people are witnessing these types of horrific things that have actually been going on for a LONG time, which is good, but not enough is being done by ANYONE weather democrat or republican to actually pass laws to better control, and prevent this type of thing.
Probably though... the biggest problem is what you described as the "fraternity of police officers." Before this last atrocity, I recall an event where a ******* white female cop was so *******, she walked into a black man's apartment thinking it was her apartment, and that he had broken in... she shot and killed the man in his own home! And, THAT wasn't even the worst part... what many media outlets failed to report was that there was another black male in the apartment that she didn't shoot, but witnessed the event. He was set to testify against her, and MYSTERIOUSLY... he was killed before that could happen!!! Obviously, by police, committing cold-blooded ******* to protect this horrible excuse of a human because she was a cop!
I can't say that I understand your pain the way that you feel it, the way that young black men, or mom's and *******'s of young black men feel it, I don't think that's really even possible, but I do feel it in my own way, and it makes me incredibly sad. I think this is a major reason we need to see more black politicians, police officers, and organizations to fight these systemic issues, and we need actual actionable measures taken to help fight these problems... like bodycams for ALL police officers, and a separate organization that can review them, and take disciplinary actions upon review just as a start.
