A few changes to detective

[Frank_Stein]

If I have to use my gun it should be because Im ready to kill.

I agree with this on theory, because I also believe the detective shouldn't be making arrests, and if they do get in a fight it should be because shit has hit the fan. 

What I think is an untapped area in Detective's potential is stealth. Their two best stealth abilities are the radio stickers and their handheld camera, which let them watch and listen from a remote location. However, there's not much beyond that.

Perhaps they could use some face mask tech for changing their appearance for undercover work like tailing someone, or a limited cloaking device built into their coat.
