It's been an exciting day in the Bay Area. We were walking up Post at around 5 p.m. and encountered chaos at Larkin Street, in which the whole block was taped off with police tape. We heard the words "bomb squad" before making a detour.

Upon returning up Hyde, we ran into more police tape and the heavily armed/armored dudes pictured above. We also saw a guy being wheeled into an ambulance. After our second detour in which we came back up Leavenworth, we heard from others that it was a hostage situation and a guy had barricaded himself into one of the buildings, which KGO has confirmed. [Update] The man was taken to a mental hospital for an evaluation.
