Guys, this doesn't seem to be "man black people sure are scary, damn am I right guys?" It's "man, this game where people assault random strangers is scary, isn't it?"
OP has somewhat of a point. I don't think drawing a comparison to police brutality is apt or even applicable really, because police are held to different standards and are supposed to protect civilians, and that's a problem that seems more widespread. The "Knockout Game" is also done by a select few morons. But, this doesn't change the fact that it is actually a scary thing.
No.
It's just obvious racist bullshit we've all seen a million times before. "The LIBERAL MEDIA is just trying to distract you with false claims of racism while DANGEROUS BLACK PEOPLE are out here preying on innocent victims, but of course THEY WON'T TELL YOU ABOUT THAT BECAUSE AGENDAS" etc.
