Live Action Mafia

I am a "vigilante." This is in quotes, because it's the role name I was given, but my actual power is to make two investigations per day, without needing to visit the murder site. I have no ability to make kills.

I received two items:
1. medkit - activate and become immune to "bangs" for a day.
2. brainwasher - tap someone and say "brainwash" to erase their previous goal and replace it with a goal of your choice.
