Olutosin Oduwole was in his dorm room at Southern Illinois University when police knocked on his door one day in 2007. They were there to arrest him.
"In my mind I'm thinking, 'Okay, maybe a warrant for a ticket.' I really didn't know what was going on," he says.
What was going on was that the police suspected that Olutosin, a college student and aspiring rapper, was on the brink of committing a Virginia Tech-style mass shooting on his campus. He was soon charged with attempting to make a terrorist threat, and was eventually convicted and sent to prison.
