chief photographer john mackenzie is here with me.ou can pan to the left you can see there's an officer there with what appears to be a shotgun, possibly a bean bag shell round keeping an eye on the roof of that building that is where that brick was from. if you look at the ground on the officers feet you can see a lot of degree on ground from where the brick was thrown. a lot of the officers disavow the incidents of that individual. they said, he's not a part of the occupy movement. officers not taking any chances. you can see the officer here in a tense moment with that bean bag gun aimed up toward the roof of the building. again, unknown exactly how many people are occupying this building as we've watched, i watched it dozens of people went in and out of the building so it's hard to gauge exactly how many are in there right now. certainly that's one of the issues that could make it difficult for a san francisco police if they win and if they decide to move into this building. you can see some of the occupiers outside of the buildin
