Radley Balko has a really solid piece on the war on drugs up at Culture 11, and really, this line says it all:
When Richard Nixon first uttered the phrase “war on drugs” in 1971, he chose his words carefully.
You can also watch Radley debate the topic at Bloggingheadstv:
Have not watched it all yet myself, but I will listen to it later on today at some point. Freddoso’s argument mainly seems to be that bad guys will just find something else to do if we end the drug war.
