Katt Williams still seems to be in an uphill battle with whatever it is that he’s battling. (Some say a mental disease, others say drugs…others say both…) The troubled comedian pulled a gun on someone at the Comedy Store in West Hollywood last night, triggering a 911 emergency that ended with 6 squad cars filled with police coming to the scene, all with guns drawn. People on the scene say that a comedian on stage started going in on Katt (who was in the audience) about his race and being short, and he was NOT having it. He pulled a gun out on the man…but eventually left before cops got there. So far no arrest warrant has been issued for him, but cops are still investigating.
