It's about time the D.O.C. got investigated, although I doubt it will do any good. 
I've heard some real negative stories from reliable, credible people come out of there. A breathing tube slips out of the mouth of a sleeping inmate and when cellmates tell the guards, they totally ignore it and the guy dies. A guy on community service for a DUI tells of the detail he was on and the van driver was drinking beer. 
D.O.C. is a closed system and they have their overseers convinced they are innocent of any wrong doings which is a BIG lie. They just tell their overseers, "who you gonna believe, us or the cons?"
Good luck investigating the real cons! (Some are o.k., some are real bad!)
