I lived in and around Sacramento for a good 20 years and from the description in your earlier post.You're bending over to explain away a situation much more readily explained by the common US phenomenon of the Po-Po liking to ticket blacks. The stats provided by the SacBee show that blacks are ticketed in disproportionate amounts to their population in that district (District 2). 5:1 compared to white jaywalkers. Period.
Further, you're speculating that these are "probably major feeders". Where do you get that information?
I have no doubt that police unfairly target blacks in Much of the US, including Sacramento, however you're bending over backwards to see only racism in this. Why not just mention the 5:1 stat in the first place. Far better evidence for racism than incredulity at the laws in question which aren't that extraordinary by internationals standards.
