Several political experts weigh in on Sheriff Joe Arpaio's apology for the mishandling of alleged sex crimes ...and whether or not he has the support necessary to retain his current position. Also, Ted Simons explains the reasons behind changes on PBS's Horizon.

Democratic state representative Ruben Gallego is among the people asking Arpaio to step down; he explains why he believes the sheriff ought to resign. Shane Wikfors, editor of onoronAlliance.com, gives his opinion on why people are making the effort to get officials they are unhappy with out of office. Arizona Republic columnist Bob Robb believes Arpaio will not resign and thinks the moment for that has passed.
