Silencer CCs miller. CCing bomb/mort is autowin for town 50% of the time (when the cop is sane/insane as opposed to naive/paranoid) since cop can check both CCs and silence can't kill. Claiming the missing PR is guaranteed autowin since cop can check sanity on miller. Claiming cop is viable but risky since a good town would have you out your report prior to the PR claiming, and a wrong report can risk autowin, e.g. giving an inno on miller when there's a mort. Claiming miller is a guaranteed 50/50, and you needn't out potentially incriminating reports, so it's the best you can do.
