There's a lot of hidden anger out there. Not anger at a white police officer or "the system" in this case, mind you. The real anger here is anger at themselves ... among professional malcontents who realized way too late in this game that they had cast their lot with a giant black dude who turned out to be a complete misfit, a loser, and a criminal as well. But a lot of these people are so emotionally stunted that they would rather double down on idiocy rather than admit they were wrong and admit disappear quietly.
Plus they know that their “15 minutes” is about up and they know that the “conservatives” are starting to take back the nation back and are now are on the “losing” end of things.
