Dunno if this is worthy of a new post, but this is going on now in NYC:
Suspicious powder incident is active at this time at Penn Station. Division 1 reports Amtrak PD is investigating a similar incident in Baltimore occuring at the same time. FD is staging, Box 8171 is out. 30-40 people who were in the car are being held, the train is isolated in the station evacuated. They are awaiting NYPD ESU to evaluate the powder..
