At least they have somewhere to contain those awaiting sentencing. Who knows where they'd go otherwise… oh right. They're trapped in the Glade surrounded by a deadly Maze… but throwing guys in there would be a sentencing in its own right.

And yet later, when Gally threatens to kill both Thomas and Minho during a Gathering, he gets off scot-free. Well, he runs off before anyone can catch him, but it just seems like one more episode where even though the rules are strict and firm, the enforcement of them is a little lax.
