T.J. Miller was reportedly wasted on a train last month and called 911 to report that a woman was carrying a bomb in her bag. He said he watched her keep constantly checking her bag multiple times without pulling anything out, and seemed to try and bail from the train quickly and leave her bag behind. Which obviously gave him the thought that maybe it's a bomb, so he made the call.
What's ironic is everyone is all "see something, say something" -- the dude thought he saw something suspicious, so he said something -- and got arrested for it. Turns out police checked the bag and everything was fine, and T.J. was said to have ordered a good amount of drinks while he was on the train, so who knows.
