Sure I'm familiar with it, I had a case thrown out of court earlier this year because the judge felt the cop had stopped the guy for exactly that, suppressed the evidence and the guilty-but not of what he was allegedly stopped for-client went free.  My point was the expansive nature of your statement is absolutely incorrect, while there certainly are terrible breakdowns and injustices, you do not get tossed into prison for fitting a demographic, at least here in N. California.  You may very well get heightened scrutiny and we can't always defeat that, but you don't head off to Soledad cause you are a 19 yr. old Hispanic with baggy pants.
