I would just like to say that Joe Arpaio is a paranoid, sadistic, racist piece of shit, and that any news article which doesn't accurately drive this point home is betraying a bias in his favor. The BBC article I linked to does an okay job of making it clear that this guy is a raving nutbag asshole, but it should have been more explicit. There also should have been something making it clear to readers that there is no legitimate controversy over Obama's birth certificate, and that those few hardcore birthers who remain are highly deluded, lying, or both.
I seriously don't know why this guy isn't in jail. Wikipedia has a whole separate article about his blatant abuses of power, separate from his main biography. The guy is a thug and a criminal, and he should be behind bars. Though he shouldn't be forced to wear pink underwear or fed moldy bread, even though he deserves it; some of us actually believe in the rule of law.
