I hate going against my gut.
I think Taiga's probably either the cop, or has some cop-like powers (although it wouldn't be unheard of for a scum to have some form of investigative ability, btw).
I'm reluctant to vote for Dannymac because 1) killing a new guy on day 1 and 2) dunno if a scum would suggest such a thing.
(It's true that he may have done a clever bluff, since he KNOWS we don't like to kill new guys on Day One, but... yeah).
So, I'll think about it, and claim that I'm not a cop.
