For me, it happened one game when I was Vigilante.
On N1, I got jailed, and claimed Escort, just in case it was an interrogator.
On D2, The Godfather publicly claimed spy and gave correct info on who the Mafia had visited. A Lookout/Detective also revealed with info on who had visited one of the Mafia targets.
On N2, using this info I shot one of the visitors, who turned out to be a blackmailer.
On D3, I revealed as Vigilante, saying I shot the Blackmailer.
On N3, the same Jailor jails me and executes me for lying to him about my role. I checked the replay - the dude was a Jailor. :c
