If you tell Shantay that you are a bindit, he will have his guards imprison you, and if you remain defiant to Shantay, he will have you taken to the Port Sarim prison. you will be traped in the only unoccupied, locked cell on the ground floor. the cell itself is very easy to escape from, even without a lockpick. The only guard on the ground floor is sleeping, so you shouldn't have any trouble walking out the front door.
