Fake Mental Incompetence Well Enough to Avoid Prison?

You’re facing charges for a crime that left someone dead, and the evidence against you is overwhelming. There’s no real way to argue that you didn’t do it. Your only shot at avoiding prison is convincing the court that you were legally insane or mentally incapable of understanding what you were doing.

You would have to keep it up through police questioning, psychiatric evaluations, court appearances, and constant observation by people trained to spot faking.

Would you even try it? If so, do you think you could actually pull it off, or would the professionals see right through you?
