First, this;
I'd like you to post the conditions of your "no lie policy" here so that people who haven't played with it before aren't at a disadvantage.
I don't like lying. I prefer to play Mafia whilst lying as little as possible both because I don't enjoy lying and also because I find it adds an extra level of complexity to the game that I enjoy having to work around. This is my motivation for having a No Lie Policy (motivation is important for those trying to figure out why I would bother with this and how I might choose to word things within the confines of my NLP).
In the strictest sense, it means I will not knowingly lie about anything in the game, except where my alignment is concern.That second clause is in there because naturally in order to play as Mafia I need to be able to claim that I am Town, so I've allowed that in the terms of my NLP. Technically, this means I could also claim self-aligned (as I have in this game) even if I were in fact not self-aligned, though positive reasons for lying and claiming self-aligned are few and far between. More likely, in every situation where I would want to lie about my alignment (ie. If I were Mafia), I would sooner claim Town than Self, so you can put some amount of faith in that claim. Still, technically, my alignment claim is not guaranteed per my NLP.
As for everything other than alignment (role info, knowledge of the game, etc), I won't knowingly say anything that isn't true. Now, I can omit pieces of information (ie. if I was a 1/shot COP, I could say I have an investigative role and conveniently leave out the bit where I can only use that ability once), but I won't knowingly say anything that is strictly untrue. The "knowingly" clause is important because if I were an insane cop and my results were reversed, I wouldn't know that I would be saying anything untrue in what I say.
TL;DR, My NLP means, at the very least, that you can believe that I believe everything I am saying is true (possibly excepting where my alignment is concerned).
Now, second, to respond to the allegations that I am potentially a threat to the town;
I am.Depending on circumstances. If the game plays out one way, I am a threat to the town. If the game plays out another way, I am not a threat to the town.
I have no problem telling all of you this because under normal circumstances (majority vote, vig, whatever) I can't die. Something specific has to happen to result in my death.
Oh, but a fair warning:
if anyone tries to investigate me to confirm what I am saying, you will unknowingly bring me closer to realising the conditions in which I become a threat to the town.
