In the US last year, 754,224 people were arrested for possession (not dealing or production) of marijuana. By the logic of US drug laws, all of these folks are better off with an arrest record and possible incarceration that they are from the nominal negative effects of smoking marijuana (FBI report here, via Radley Balko). These numbers are just insane. And while the report only gives race numbers for total drug arrests rather than for just marijuana offenses, a hugely disproportionate number are black (over 1/3 of arrests).
And speaking of equal protection, the arrest numbers for gambling are eye-opening (table 43). 75% of all people arrested for gambling last year in the US were black, including 90% of the arrests of those under 18 for this offense. It seems it is A-OK for whites to play poker at home for money (I'm guilty) or to bet in Super Bowl pools (guilty again) or to clad themselves in polyester and head to the casino boat, but blacks who choose to compete with the state gambling/lottery monopoly will get arrested. As an aside, I have always laughed at the government piously suing tobacco companies for targeting minorities with their advertising and then using the same techniques themselves to target minorities for their lottery sales.
