I don't know if you're harmless, but you're a C.
You, Gabe, Sab and (possibly) Melo are too suspicious only because you're all too confused, not because you're gangstas.
Matt is fucking unpredictable. No way to tell what's his role even though everything points out that he's a G.
For Janna it's the reversed. Everything points out to a C, but even Janna can't explain what's going on in her head so how can we do it?
That leaves Osman, Kate, Kyle, Nate, ALC and Cheese. Two, three or four of these 6 players are gangsters. Most probably 3 or 4, not two. One of the first two are probably the recruited G, ex-civilian.
