From the abstract:
This 127-page report details incidents in which correctional staff have deluged prisoners with painful chemical sprays, shocked them with powerful electric stun weapons, and strapped them for days in restraining chairs or beds. Staff have broken prisoners’ jaws, noses, ribs; left them with lacerations requiring stitches, second-degree burns, deep bruises, and damaged internal organs. In some cases, the force used has led to their death.
