The self-righteous indignation of the justly persecuted.
I don't recall if the building was guarded or not, if it was, it would probably have been just one deputy, or maybe a rent-a-cop. These guys would have overwhelmed just one officer, especially since they weren't technically breaking any laws, just "peacefully demonstrating". But watching them was something else, they were like frat boys at a hazing, they were angry and loud, and dripping with venom.
