So let's keep entertaining the idea of a target switcher. Do we know the alignment of this person? No. Is it safer to bet that this person is mafia? I think it would be. Do you think it's probable that the mafia might switch him with town? To create a false-positive I'd bet my sweet ass on it.
I prefer a more scorched earth policy for, like I said, 100% certainty.

Actually it wouldn't, it would keep you in the nebulous realm of uncertainty that so far everyone is in to my eyes.
