Mafia 101. Disputed Island

For now, the best approach is to examine each clue individually, first verifying its validity. I've only glanced at them briefly, so I'm not ready to give my final verdict yet.

Well, that's just awful. Clues were always a shaky foundation, but now it's hard to even talk about the validity of the solutions (not the clues themselves). At least, that's the case for now. However, we need to keep digging, and the clues should serve as a basis for discussion; that's their role and that's their advantage.
