Partial but significant blame goes to the media and the D Rats for foisting these pseudo claims of racism on us all like a constant drumbeat. Unbalanced savages like this demon get riled up over it and look what happens. Innocent people being murdered by DemoRat beasts.
Just like they tried to do with blaming Sarah Palin for Giffords, and the racist circus, false accusations re Geo Zimmerman and Darren Wilson.
The majority of the blame falls squarely on the usurper, Moo, Holder, Al, Jesse, Rev. Wright, Farrakhan, #black lives matter, RATs and the lying msm. You know his daddy soetoro is pleased as punch.
