Dealing with Scum Bus Drives

[Battousai]

It depends on the role (assume player A is the intended target, while the action has been redirected to player B)

Investigative: Player B is innocent/didn't visit anyone
Protective: Usually doesn't get a result normally, so doesn't get one redirected
Killing: Usually doesn't get a result normally, so doesn't get one redirected

You shouldn't tell the player that their action was redirected no matter what, though when you give them "Player B is innocent" they can pretty much infer it, when they ask if you made a mistake and tell them no.

I prefer not to fuck with investigations. It's a little bastardly. I always tell my cops Player A is innocent/guilty or that the investigation failed.

Protectives and killings do not recieve confirmations anyways, so I wouldn't give them extra information.
