ModPCMiscStat [Name of Stat] [Number] <-- This can be a negative value (ie, -10)
So for example, if you suddenly find you have an Assaults stat of say, 5 you would enter:
ModPCMiscStat Assaults -5
Then your stats would show Assaults at zero.
You can actually alter all your stats using this method, but obviously, this is for PC users only. Unfortunately, console players are stuck with what the game does by default.
Apologies if this command was actually more well known than I thought. I just saw a lot of posts complaining about the game's tendency to accuse you of crimes that you felt you hadn't committed.
