SFist reader and all-around awesome human being Chris Wiggum writes to us, letting us know:

Mission between 10 - 11 has been blocked off by police. The bomb squad apparently has been called in and several people were rushed off in an ambulance. Not sure what's going on, I just spied it from afar. Checked SFist to see if it had been reported - have you heard anything about what's going on?

So far our phone calls have been unanswered, unreturned. But while we figure out just what's going on, do you, dear readers, know? Let us know. Thanks.

Update: All is clear now. Just checking out a suspicious package. Nothing to see here, folks. Move along.
