I guess the term should be altered to "Pressure all liars." You shouldn't auto-lynch but it definitely warrants pressure if the player isn't doing it for ProTown benefits.
Also, for people curious why I rolled with the BP claim, I didn't see the benefits from retracting it afterwards. Yes, it gained me more trust, but had I managed to make LyLo or MyLo, I would've been in a very nice position regardless and I was banking both on my ability to get out of tight situations during the day and on a vig wasting his time with an inactive, saving his shot, or not being there at all. A cop investigating me would've been gravy.
