Mafia 101. Disputed Island

Well, I've already essentially written that I'm okay with Alex being executed. I have no guarantees that he isn't Mafia, but since there are so many suspicious people here...

How am I more suspicious than Alex? There's just as much information on me. And you're not a blocker, so you wouldn't have any additional information about me.
There's actually evidence against Alex, and in fact, there are two pieces, but I don't consider mine to be very good, so there's really only one. But it's a good one.
