The only problem is, the princess happens to be Twilight and Twilight has no idea what to decide.

She embarks on a little journey to try and find out if she should better throw somepony in jail, risking the fact that he might be innocent, or setting him free, risking the fact he might be a danger for society. And therefore decide how much is worth sacrificing for the insurance of safety.

By chance, there is always the option to rely on princess Celestia as she always knows what should be done.
