He is being held at a Detention facility right now, not a disciplinary facility.
I work as a Detention officer (the guys you see in the videos escorting), we are not 'pigs' or whatever else. DO's job is to simply make sure the guys waiting to get committed live in a safe environment and sometimes we have to enforce rules for the inmate's safety or our safety.
I can guarantee you, Titus must have posed himself as a serious threat to officers if he was being escorted by all those officers in riot gear. We use a chair like that for the mentally disturbed people, whom exhibit traits of a very high pain threshold and are extremely dangerous. They are held in a padded cell with 15 minute watch.
My opinion: The number of guys in that video were a bit excessive but they did everything 'by the books' which might be ridiculous to you, but there are inmates that will sue you for any fucking thing. Alot of DO's can evolve into a jackass over time and I follow the rule that you treat everyone in jail like it is your mother & everyone makes mistakes.
