I helped Seargent test many of these new weapons/tools and they were all very fun to use, I can definitely see the issue with detectives running around randomly handcuffing people and randomly finding T weapons. However, as Sergeant said the Traitorifier has a crazy low success rate. Just trying to show me what it does, it took about 8-9 tries for it to actually work so it really isn't that op(if that is a concern it could be a 2 credit item or something to balance the purchase.) But I do remember the grav grenade put me inside of a wall when I got hit by it, so it would most definitely cause something like that with a large group of people on a small map like the one this server uses.

Traitorifier, Drowning Indicator, and Freeze Gun would be very fun additions in my opinion.
