Last time I looked at the stats, 18-30 male is the demographic most often arrested. Black 18-30 male get arrested slightly more often than white 18-30 male (although not as much as you'd expect). If you looked at the numbers and nothing else, the truly "privileged" demographic is actually Asian females. And for the record, yes I'm in the 18-30 male demo and yes I've had a police run in which didn't end in "sorry officer".

Now conviction rates are another story...
