Forget the county jail!
Have the punks take a tour of the frigging penitentiaries that house the worst of the worst. Take 'em for a stroll down Death Row. Give them bread and water.
San Quentin, Corcoran, Sing Sing, Rikers Island,etc. Mix it up a bit.
It's boring now because all they do is have the inmates and the guards yelling at the kids.
Put your trust in the Lord. Your ass belongs to me. Welcome to Shawshank.
