A friend of mine from college was a bank teller who was robbed. She told me the story of having to undergo an intimidating post-robbery interview with two very serious FBI agents. I don't know if FBI agents investigating a bank robbery suspect everybody, or just bank tellers, or just my friend in particular. But what with all the video cameras and all, I don't think it would be so easy for a teller to get away with pretending to be robbed.
