This right here seems to be correct according to several sources I just looked up. I've actually read and heard this more than once, but for some reason certain people can't accept facts? Do they want something to rage about so they create this "systemic racism" or is it something else?
It's a couple things. They're not stupid people, many people just prioritize emotion in life. So when the media puts up a big flashy title card that says, "UNARMED BLACK MAN SHOT BY OFFICER" Every other week, people start to get the wrong idea and think this is some systemic massive issue.
It doesn't help that the media perpetuates lies and misinformation about the cases. For instance, they stated Michael Brown was gunned down in the street for no reason with his hands raised. Not true; The official investigation determined that Brown had robbed a convienence store shortly before the incident, was stopped by an officer, and then charged at the officer in his vehicle. Brown tried to grab the officers weapon inside the cab when he was shot. The autopsy supports this.
But all you'll ever hear is, "Hands up, don't shoot!", because that's all the media covered and wanted to be true. It's all really disgusting, it's just lies and misinformation.
And all this isn't to say that there aren't racist or brutal cops. When there are actual racist or brutal cops, they should be prosecuted and prisoned to the full extent of the law. But cherry picking a few bad cops (.9% in fact) and applying that to the VAST majority of 99.1% of officers who NEVER engage in any misconduct is completely unfair and faulty.
America doesn't have a systemic or consistent police brutality or racism issue. However, the evidence and statistics DO display that we have a cultural and gang related problem in inner cities, like Chicago.
