If your concern boils down to a lack of trust of Jamie, I can see your point, but I would nonetheless argue that Jamie's proposition does pose inherent disadvantages towards the anti-town factions since the plan entails a weeding-out process. Of course, this at face value does not account for the kicker that a mislynch presents given we only have so many opportunities (granted, this notion is sort of redundant).
Going back to Jamie, part of me does wonder whether the strategy proposal could be an attempt to not only gain potential town credit, but also use the proposed strategy to manipulate the town agenda? While I consider this, I ultimately find this unlikely at this time especially due to the strategy's systematic weeding-out mechanics. I don't think scum would want to risk posing something so potentially risky for the team if the town plays its cards right. This all being noted, Jamie's proposal does give me town vibes.
