Excellent story, Rui. Well done. 

BTW, someone with Mild MR in the general prison population is worrisome,  but if Mr. Medina had MODERATE MR,  this would be very worrisome. He would have been clearly vulnerable to abuse in a harsh institutional setting. His face really tells the story.

Consider:

Moderately retarded individuals have IQ scores ranging from 35-55. 

They can carry out work and self-care tasks with moderate supervision, and cannot typically communicate on complex levels. 

They may have difficulty in social situations and problems with social cues and judgment.

They can be easily teased, bullied and victimized and are unable to verbally advocate for themselves when this happens. Many experience frustration about unfair treatment and resort to aggression which can escalate interpetsonal difficulties.

Lawsuits and advocacy are needed to protect such persons, but the DOJ civil rights division rarely enforces CRIPA these days.  Barbarity and PR coverups are the norm.
