Further thought shows that if Barney is untargetable, he is essentially scum's Godfather equivalent, so the Kanji wagon swing still worries. I also haven't been convinced that the Duff Beer interactions don't look horrible, town doesn't want to deny town information. Alpha still irks me in all honesty, but his situation was different because he was affected by Duff Beer personally. Barney was just trying to stop Duff Beer's role from being used on another player.
So no, the claim doesn't alter my take on the situation. However, I'm still willing to hammer Bardiche if we need the lynch and nobody else is around to, because his D1 still looks quite horrible to me. I just find Barney harder to buy because it looked like he smokescreened in an attempt to stop an investigative role from being used, and that was really the deciding point against him for me today.
Going to re-read anyway to see what I find, but I don't expect it to be particularly mindblowing.
