Both cops claim D1, which gives you two confirmed cops which will obviously produce a town win, so scum is forced to counterclaim. This divides the game into 3 cops/4 unclaimed, with one scum in each pool. You force the Doctor to claim, which scum cannot counterclaim without producing two confirmed townies. You then lynch one of the three unconfirmed players - if it's town, all three cops target the other two unconfirmed players. Scum is forced to kill the Doctor as it's a confirmed innocent, and too much of a risk trying to kill a cop which might be saved. Since all three cops targeted the same player, you get a result, which confirms the last two players' alignments, giving you an automatic scum lynch. There will either be three cops left which will produce a 50/50 3p lylo, or the confirmed townie left which produces a 50/50 3p lylo. This is a worst-case scenario for town, which can obviously be improved on in the 1/3 games where they hit scum on D1, which is an autowin.
