> 1: It really varies; surprisingly enough it's not a felony in all states, and in at least one state, it's only a felony if there is intent to benefit from the authority granted.

You think that's surprising? Wait til you hear that in 35 states, a police officer can claim that a detainee, in custody, even handcuffed at the time, can 'consent' to intercourse with the officer. (That's even before you get to the lesser issue of why a police officer is having intercourse at work...)
