I'd just go back and copy / paste whatever you said about why QVist would let you investigate.
You think I, as scum, would prefer to gamble on Eevee being the Cop rather than switching off the Cop and killing almost-certainly-the-Doctor Munch?
I mean, yes, scum did that. And from where you sit, that's explainable as either newbie scum Qvist making a mistake, or crafty scum Volt purposely making a "mistake" that you wouldn't think Volt would make. So I guess this has to be a null point in your analysis.
Which is why I ask you to look at ash's and joth's behavior instead. Any explanation I give for my own behavior can be met with the "well maybe you did the opposite of what I'd expect because you're crafty" response. I mean, look, how can I respond to that? I try to be crafty, I admit it! I'm crafty
regardless of my alignment!
So look at joth and ash instead. Does their behavior fit as scumpartners with Qvist, or as scumpartners with me?
In particular: Do you think that, if I were scum, joth and ash would have bandwagoned immediately on the yumawagon that I proposed at the start of Day 2, given that we would have had no opportunity to plan such a stratagem ahead of time?
Or do you think it more likely that scum!joth and scum!ash joined a plausible case I started, scum!Qvist expressed reluctance because he was scared to scumhammer a wagon with all of his scumbuddies on it, and then was stuck at being unable to finish the job when all the other townies balked?
