Thats a pretty adamant position:

There are a number of examples.. here are a couple:

Jospeph walker a black guy, who shot a white road rage aggressor. He walked free.

Here is a white guy shooting a black woman "in self defense". he got 15-32 for that.

While there is definite bias in many cases, it's definitely not all "Good for the white guy". And without diving down into each and every case, painting everything with the same brush helps nothing.
