Detectives, their gun, and supercopping.

[Frank_Stein]

The Detective is security, it's just that the intended focus is that you're supposed to be the the flavorful investigative branch of it rather than the enforcement.

But that is beside the point. In any given round you don't know who will be playing what roles. That's why Security has forensic scanners in their PDAs as well as one in the room. It's overlap in case there's no detective.

Which is why I think taking away the Detective's Sec access is a bad idea. What are you supposed to do if there's a Detective but no Sec? There's got to be some flexibility in the roles.
