Corrections sergeant(a promotion I kind of regret taking now) actually but yes I'm in corrections but I do have full police powers with the exception of effecting traffic stops. There are things like departmental policy when it comes to carrying off duty(I'd go into details and am quite sure you'd roll your eyes at them with me) but in reality we are exactly like a street cop only the crooks and other bad guys are easily identifiable.
Is this just a NJ thing? The CO's that I know do not have any power whatsoever outside of the prison.
