Rumors that someone had the locks changed on San Diego Mayor Bob Filner’s office while the mayor stepped out for a two-week course of intensive therapy to deal with his “hugging” problem turned out to be true, with several news outlets confirming the story Friday afternoon.

That wasn’t the only surprise in the Filner saga today. Sen. Barbara Boxer penned an open letter to “Bob” urging him to step down immediately.

Let’s not be hasty now. Why should Filner step down after all, now that he’s been cured?

Details about the lock change and the reasons behind it are unclear. Can Filner trade a note from his therapist for a key?
