Don't worry, Flutters.

If Equestrian law is at all like Anglo-American law, you can't be guilty of a crime that someone tricked you into doing.

You have to have the requisite mens rea (mental culpability, essentially).

You'll be out in no time, and Pinkie will be in the Equestrian version of St. Elizabeth's (the hospital in DC for the criminally insane, like Pres. Reagan's attempted assassin).
