If black people committed more crimes than white people, but were treated exactly the same in the criminal justice system, there would be no racism. That's not the case. Crazy didn't have a rebuttal to the sentencing data, because it's damning. So is the ticketing data, which he basically admitted was due to racism.
Of course, unless you believe in genetic inferiority, the black crime stats are due to the environment they reside in, an environment that people such as yourself would die to protect. If you vote for Trump, it's game over for that argument.
