Arizona Sheriff Joe Arpaio on Trial

As Sheriff of Maricopa County, Joe Arpaio became famous for holding detainees in tents under the blazing Arizona sun and for making inmates wear pink underwear. But it's his focus on immigration enforcement – what he calls "crime suppression" and the plaintiffs call "racial profiling" -- that's led to a class action lawsuit scheduled to open tomorrow in a federal courtroom in Phoenix. Will it hurt him or help him in this year's campaign for a sixth term? Will it move Washington any closer to immigration reform?
