This is a little bit of good news. The total prison population went up last year, because there are more federal prisoners.
The boom in prisoners comes mostly from imprisoning drug dealers. I am all for imprisoning people who commit crimes, and drug dealers, as a group are vile.
Still, I think we should legalize marijuana and tax it heavily. In fact, I would be happy to dedicate the pot tax to fighting the really bad drugs - there seems a certain poetic justice in that. If we extract marijuana from the war on drugs, we can devote our prisons to the worse criminals.
