Are you suggesting that jaywalking laws exist to target blacks exclusively? Given that pretty much every jurisdiction on North America has these laws on the books, that's a stretch.
Remember, I'm responding to the allegation that laws are specifically designed so that everyone breaks them, not that there is selective targeting.
First, I don't agree that laws are "calibrated" (by design) such that most people are likely to break them.

"I'm responding to the allegation that laws are specifically designed so that everyone breaks them, not that there is selective targeting."
Consider that the selective targeting aspect is far more important than whether the laws were designed so that they facilitate selective targeting, or just happen to facilitate selective targeting. Either way, selective targeting is something that should be avoided.
