You are sadly misinformed on a few points, inmate Hermione Granger, so I will correct that.
No inmate in the history of this facility has ever been permitted contact outside the asylum. Inmates who show a sincere desire to reform, who have consistently nonbelligerent and nonviolent behavior towards the warden, facility property and other inmates will naturally receive better treatment and protection from this system.
And, every inmate present in the facility has already received a trial, and thusly been found guilty. It is an irrefutable verdict.
