Hmm... I dunno... well, you really have to be careful if you want to survive here. After all, even a Townie needs to be careful in order to survive as not to make people suspicious of him on my first try. And I should know, I've been in another Mafia game over on LoZ.com in which I wasn't very careful and got lynched on the first day even though I was a Townie.
Anyways, while we can tell whether or not others are scum based upon how careful they are, I can't say. After all, some may simply be naturally careful while collecting evidence, while others are usually pretty aggressive in the way they play. Really, it's all about play style and since this is the first game for the vast majority of players, we can't tell whether or not their scum based on how careful they are.

Also, yeah I agree that the SK needs to die. If we let him live, then our numbers are reduced by a possibility of 3 (Vigilante, LOL) each night, in addition to whomever got lynched (a possibility of four). And we've already had our numbers reduced by three, so yeah if we let him live that only makes things extremely hard, if not impossible, for us. After all, there are 24 players total, 7 of them are scum, subtract 7 from 24 and you get 17, not to mention our numbers have been reduced by 3 so that only leaves us with 14 Townies.
While it may not seem like much, if we let the Serial Killer roam free, that's at least two Townies dead a night, with the possibility of us lynching a Townie on accident as well as the possibility of the Vigilante killing a Townie, so yeah. Not good for us.
