COs think they get to define the limits because in their little correctional kingdoms they do. Whatever they say goes, right or wrong, the inmates are always responsible for the bad conduct of the COs, and the DOC backs the COs up 100%.This is no different than when the police backs its officers and the public let's them off scott free after they bully and kill innocent citizens. Their get out of jail card is the phrase "I felt in fear for my life."
