Anyone believing the majority of this type of behavior isn't the direct result of the left's race baiting politics over the past 8 years is delusional.  

When issues of police violating INDIVIDUAL rights exploded in lame stream media, it was framed in context of race (despite the fact more whites were killed by police)...an issue the entire country could have worked on TOGETHER.  That issue was hijacked.  The party of race-baiting/victimhood (democrats) and their apparatus of prestitutes succeeded in a narrative (racist police wantonly killing) having little to do with reality.  

Keeping a country divided along racial/religious/ethnic lines is the Bolshevist game plan.  It helps destroy a middle class, divert attention away from the fact we have it better than anyone else on the planet.  Globalists don't want you to catch wind of the fact our socioeconomic system (despite some flaws) has done more to move civilization forward, in shorter amount of time, than anything before or since.
