I am not being sarcastic. Since both motion trackers claimed, both teams go into Night Actions knowing full well who will set off a motion tracker and who wouldn't. If Scum is not next to a motion detector, they can freely target those next to a motion detector with no repercussions. In fact, they can do so with benign powers to make said person look guilty. Even guiltier if a person was already dinged by a motion detector.
Easy scenario: You are a scum role blocker. At this point you have no real idea who the other PRs are with active abilities; Scrafty and Camjo are read; Ouro is on drink break. Previous night phase, Launch set off a motion detector (since we doubt Burbeting did). Who do you target?
You target Launch. Even if he has no PR, he looks like he does because twice in a row he set off a motion detector. If he does have a PR, his action fails AND he looks suspicious.
Or quite possibly Launch has a PR and is moving. Unless it was mandatory, he would be dumb to do it while next to a Motion Detector, unless it's an important role.
Or he is Scum doing something.
While I might think 2 or 3 are the most likely, 1 is not an option I am willing to dismiss. It's a good scum play, given Launch has several votes on him already.
