My dad works...

At a major university in Detroit, and he said that if there is a robbery on campus, or in midtown, they are instructed to call the campus security and /not/ the city police. They apparently respond faster. So that could be an answer to why the MIT security was there. They call campus security, the guys see him and panic-shoot him?
