I'm not sure whether this has been suggested or not, or if it's in the wrong place, but I felt that I needed to share this idea with the devs.
I had an idea for a Detective Item: Handcuffs. You only get one pair, and they are reuseable. If a/the Detective dies while someone is cuffed, someone can pick up the keys and take the cuffs off of the cuffed player, receiving the handcuffs themselves. If a cuffed player dies, only the player with the key can take the cuffs from the dead.
A cuffed player can not use ANY weapons, OR the USE key and is basically holstered.
This could be good against anyone who is resisting 'Ammo Checks' or 'Testing Chambers'
So discuss amongst yourselves. If its already been suggested, sorry for resurrecting a possibly dead idea, if it wasn't, then woohoo!
