@Uninvince, gotta agree that the weapon serial number checker isn't nearly as useful as the other ones. What if you could also check the fingerprints on weapons to see all the people who've touched it? That way you see the murder weapon, find it, and identify the killer or at least make suspects.
I like how you left out the part where I explained why revealing 1 player's innocence doesn't obliterate all sense of mystery and makes everyone trust and love each other. Great logic.

Seriously, maps have traitor checkers all the time. The game isn't exactly ruined when they're used (in fact, they're made more interesting. I'll say "everyone put citizen on friend he's clean" and set him to kill on my scoreboard because I'm traitor and I want confirmed innocents DEAD).

We're making 1 player innocent, not half the server. His role as the bastion of innocence creates even more tension and paranoia. Who's out to help the detective and who's just pretending so they can get closer? Maybe an innocent leading the detective to a body is actually a traitor leading the detective into a trap. You're obviously terrible at this kind of thing so I'd probably just stop typing if I were you.

Protip.

Don't use the pistol for head shots then.

I believe I've found and fixed this. You did see some of the traitor menu, right?
I'm afraid I really don't have any intention to suffer posts like this. You're banned.
