Rick, I don't have statistics to respond to your question, but in doing a jail inspection a year or so ago, I was struck by the differerence in the quality and quantity of supervision between a direct supervision unit and an older jail that had multi-person tanks in a linear design where staff only saw what was going on when they walked down the corridor and looked into the window of each tank. Even adding video surveillance to the tanks leaves them supervised only a fraction of the time that a direct supervision unit will be under the eye of a staff member.
