This is obvious. It never failed for me. Are there others ? I read smth about two Witness Evidences or one Witness Evidence and fake/no alibi but I'm not sure if they work 100% of the time. Has anyone found counterexamples ?
I once got all 5 people pointing at one guy.
The 7th person was dead.
The evidence pointed and the dead guy and the one that all of them suspect.
And he was the only one that apparently has no Alibi.
Lol, how lucky was I?
