Phoenix New Times:  “Maybe one reason marijuana prohibition is still in effect is this: Law officers face being fired merely for stating publicly their views on legalization.  That was the case for Joe Miller, a former Mohave County probation officer whose supervisors terminated him after his name appeared on a letter — with 31 other law officers — in support of the 2010 California ballot proposal that would have made pot as legal as booze and cigarettes.  Now Miller is suing for damages in a federal complaint with the help of the American Civil Liberties Union of Arizona.
