Say that there's an escort claim that you're sure is a consort. You are a veteran.
You're suspicious that a certain player is a consort, but town either disagrees with you or is preoccupied with another target. Here's what you do:
1. Claim vigilante.
2. Announce several times to the town that you are shooting the suspected consort tonight. Make sure the suspected consort sees it.
3. Alert that night.
If it is a consort, they will think you're a vigilante and will roleblock you so they don't die... and step right into your veteran booby trap
(This has happened to me and worked like a charm!)
