FYI: Legalized and decriminalized are not the same thing. A professional prostitute and political activist named Dolores French (http://www.amazon.com/Working-My-Life-As-Prostitute/dp/05756...) was for decriminalization and against legalization. She claimed that legalization typically involves regulation of a sort that is often no better for sex workers than the violent pimps that are so frequently decried as the cause of everything that's bad about sex work currently.

They aren't the same thing and the article here specifically uses the term decriminalized.
