Condemned

Sheppard's team stumbles upon a technologically advanced society, the Olesians, on planet Olesia who purposely leave their criminals on a penal colony near the Stargate, for the Wraith to discover them first. But after the prisoners shoot the jumper down, they discover that this punishment is too effective and the crime rate drops, forcing the Olesians to start sentencing petty criminals and innocent people to the Wraith.
