Greatersford is not just your WOD refuse pile. These are some serious psychopaths. Oddly enough, the system should be a real present to the DOJ if it is what's going on. Just follow the inmates on release, monitor their contacts and movement, tap the phones and buildings of their mentors, and presto.....easy pickins.
As long as you can get the judges in philly to keep quiet on the warrants they sign, which is about as likely as Paris Hilton becoming the next Mother Theresa.
