This Reason article has interviews with three former drug warriors. As I discussed below, there are problems not just with the WOD, but with legalization as well. From the article:

What do you do when you legalize it? You are the government crack dealer and a 14-year-old kid comes up to you. Do you sell it to him? If you say no, then you're already talking about another prohibition, another market. So what do you do when you sell legal crack to a guy who's 30 and he turns around and sells it to 15-year-old kids? That's illegal! It doesn't work. And, then you get into other drugs like Angel Dust, methamphetamines, LSD. What do you do with that stuff? Is it legal? You are talking about stuff that directly affects the public safety.
