Mike Banning: Here's a game we can play. It's called "Go Fuck Yourself." You go first.
When one of the terrorists fires an RPG into the security hut, all the windows in the cars standing nearby shatter. Ordinary windshields are made of laminated glass that doesn't shatter, not to mention that at least the SUVs used to transport the President and his escort would surely be armored and therefore possess security glass.
