I could cite any number of studies by reputable sources, from the ACLU or from various local crime reports and it wouldn't matter because these days people just believe what they want to believe and blame the media when they hear something that doesn't fit their worldview. The only possibility I'll accept is that MAYBE people are more likely to report incidents like this these days because active racism is more outside the accepted norms than it was in the 70s and early 80s.  But even asking this question is telling on your part--one would be too many.
