With friends like these, who needs enemies?

The draft analysis, obtained by [newspaper], shows that the [train system]'s four tunnels are structurally fragile enough that the damage from a bomb small enough to be carried onto a train could allow 1.2 million gallons of water per minute to gush into a tunnel and flood the system. About 230,000 people use the [train system] each weekday. This is the article I referenced in my earlier post. I've actually decided not to post the entire text or the link, because I feel that it should not have been posted in the first place. Can't you see it now? News source: News at 11, this city's train system is vulnerable! Terrorist: Really? Which trains? News source: The four tunnels of this particular line... Terrorist: They must be reinforced if they go under water, you can't drive a truck into there... News source: You'd only need a bomb small enough to be carried onto a train in a medium-sized backpack... Terrorist: Oh. News source: Miiiillions of gallons of water... Terrorist: Oh! News source: Drowning or stranding 230,000 on a weekday... Terrorist: Oh!! Can't be good, right?
