I see it as follows: there is 1 Nod among Mojo, Orange and iLTS
Mojo - jump on Louis is a kinda shitty argument, given we were all bullying her to shoot somebody in the first place. Game hasn't then proceeded much out of joke phase, so i can't see how that would condemn Mojo. On the other hand, it doesn't compute with me why he wouldn't shoot back at either Orange or iLTS. Perhaps he's waiting for Day end? I'd prefer to conserve my ammo too, but if there was a constant threat over my head that i might be shot again before the hammer, i wouldn't hold up.
Orange - shot mojo. Completely unasked for. There is not a fat chance in hell you could be convinced someone is scum in the first half of the first day. Trying to justify it as such would work if you were, say, a rifleman, a pretty much useless role with a below 20% kill chance. But Orange claimed something more powerful than a rifleman just after, so why waste the shot? To become a non-threat?
iLTS - Jumped on the Mojowagon. While I don't like Orange's gunblazing, i doubt scum would shoot first. iLTS looks like he hopped on the gunwagon, which lights all the wrong bulbs for me. I saw a post somewhere saying iLTS' shot was justified because Mojo threatened him, but I can't remember it and i can't be arsed to look. If anyone's shot was justified today, it was Mojo's, who hasn't shot at all.
