Nonsense. I can't know it to be a falsehood because it is a fact.
That's utterly impossible. Since I'm not like that and I allow what you say I disallow, you cannot be right. Since I've told you repeatedly that you are wrong and explained it to you, you know your statements to be false.
Either a character in that situation with the knowledge that character has can do a particular action, or that character in that situation with that knowledge can't. It doesn't matter what the player knows or doesn't know.
Anyone can do the action. It's not about whether or not the character can do it. It's about whether it is cheating or not.
That is thought policing, and slowing the game done for no benefit at all - especially because you either ask each and every player to explain their character's reason for each and every action they ever take no matter how many times they have or haven't taken that action, or you are being inconsistent and only asking for an in-character explanation when you have decided to suspect the player having the "wrong" reason for doing something.
Judging based on actions and in game reasons, and not thoughts, can't be thought policing, because the thought behind it doesn't matter.
