Americans: U.S. Transit Attack Inevitable

I've been saying this ever since I took the train from Baltimore to NYC back in December. I printed my ticket from one of the credit card kiosks, so no one checked my ID to see if it matched the name on my ticket. No metal detectors or X-rays for passengers or luggage. Even if you've never been there, you can imagine how crowded and busy Penn Station in New York is on any given day. And it's underneath Madison Square Garden! The explosives the bombers in London were carrying weighed less than 10lbs each. Imagine if they had all been together on the same train instead of in four different locations.
