Yeah, i'm definitely with you on this getting uglier. The worst part about that building is that it's like a fortress. All of the windows are rather small and set high, and that doesn't count cubicles and other areas. There are conference rooms, a small auditorium and other nooks and crannies they can hide in. Pittsburgh Police snipers are good, but catching someone in there would be threading the needle. SWAT is either going to have to flush them out, or go in and get them.
