After the killing of Osama bin Laden, we knew it wouldn't take long before that one comment about bombs and terrorism brought Bay Area transit to a screeching halt. This morning, during commute hour, BART booted a man off the train after he was reportedly scaring other riders with his chatter.

Media outlets are reporting that at about 9:20 a.m., the man started telling passengers “you should be aware of weapons of mass destruction.” However, it wasn't clear what the context was —  whether the man was making threats or whether he was just talking casually on the subject.
