michael stafford knows a thing or two about violence. >> i got shot in the head years ago, and i got a big old hole here behind me ear. the bullet went in underneath my eye and come out. >> i looked out there and seen a car going down the street. i thought, damn, there is a world out there. it's been so long since i seen a car. >> but stafford has now left the cell with a view to the detention unit where he'll be locked up. the disciplinary board has found him responsible for the stabbing of pat ellerman.
