"Try to lynch town" yesterday? Except that the backup case folks have pursued all game has been... Gandalf. Looking back on day 3, he didn't really chime in with anything, just hung back and waited for the mass claim to play out. Very clever choice of what to claim - tracker's not quite a cop, so there's a minimal risk of a counterclaim, but by hanging back that long he got to more or less fakeclaim cop and reap the benefits of "Yeah I saw Rincewind!" once Rincewind started to come under heavy fire anyway.
As far as the line of argument goes, look at the situation from scum's knowledge - scum knew at the beginning of day 3 that they attempted to NK Nimitz and it failed. They knew, therefore, that in all likelyhood there was going to be a doc claiming and confirming Nimitz. Note Rincewind's pre-claims post and suspicion list. Nimitz is carefully listed as neutral, Terminator as townie (since no one but crazy John Freeman would buy his lynch), Jabba is up at the top and John Freeman is next with Gandalf lower than both (despite Rince having been on his case all game). Plan A and Plan B, and scum only need to get one of them lynched to win.
So Plan A claims doc, Jabba's no good. With Nimitz alive, there's no way to take it to 3 man and convince John Freeman to take out the Terminator. John Freeman therefore has to be the winning lynch for the final boss. Rincewind immediately comes under heavy fire. Gandalf still has that lingering trust issue.
Does the final boss Gandalf try to make a claim he saw John Freeman and push to lynch Freeman right then, alongside the Rincewind case and lingering suspicion on himself? Risking that town will not believe him (since John Freeman, previously Gandalf's biggest ally, sure won't)? Or does the final boss play it safe, claim to have seen Rincewind, gain trust for an accurate result, and then step on John Freeman the next day?
John Freeman is aware this logic does not clear himself in any way (in fact it can all be applied to John Freeman in reverse), but Final Boss Gandalf's "If I was scum I'd have gone for the quick win instead of gaining trust for my fakeclaim" gun does not hold any bullets and John Freeman is at a loss to why he would claim that as his defense.
MORE IMPORTANTLY
John Freeman would like to point out again Rincewind's lack of any effort at all in trying to rebut Gandalf's result. With most of town having trust issues with Gandalf anyhow, if Gandalf was town it couldn't have hurt scum to at least try to refute him and hope a couple of people bite. Especially, again, if John Freeman had been scum with Rincewind and could have joined on and said "I don't really trust Gandalf." THAT would have been a relatively easy route towards a scum win, had John Freeman been scum.
EVEN MORE IMPORTANTLY
Of particular note is that Gandalf used the exact same "Hey guys if I was scum I'd lynch town today and WIN!" line yesterday in an effort to spur doubt about himself and the Rincewind lynch! This came off at the time as just LYLO nervousness, but in hindsight slash just thinking clearly, Gandalf himself is the one claiming to have caught Rincewind in a lie - why is he nervous at all and not the person most of all going "Yeah this is open and shut" (and voting Rincewind immediately upon seeing his vanilla claim, for that matter)? Rather than Rincewind being the one trying to get people off Rincewind.... if people bite either way, and do turn on Gandalf, then Rincewind gets the credit for having been falsely accused by the lying scum.
John Freeman unfortunately has to sleep soon and won't be available for some hours. John Freeman... has pretty much said all he can think of to say here, though. John Freeman apologizes for the length of this post, and for being disinclined to keep up the RP much in it. John Freeman hopes people can understand the circumstances.
