The escape of 3 murderers from the MTC prison in Kingman, Arizona, was facilitated by MTC's inability to properly secure, staff, and operate a prison. Among the issues that contributed:
Floodlights were burned out.
Officers had inadequate firearms training and weapons were not well inventoried.
75 percent of the inmates did not wear proper identification.
Apparently the facility had a highly-malfunctioning alarm system that had gone off 89 times during the course of the day the prisoners escaped. So the staff had begun to largely ignore it, sometimes taking more than an hour to check on it.
The control panel that showed the status of the perimeter fence was riddled with burned-out bulbs so it couldn't be properly monitored.
One of the guard posts supposed to be maintained near the perimeter fence was vacant for most of the day. So no one saw the prisoners walk out of a dormitory door that had been propped open (though it was supposed to be locked) with a rock and climb over a chain-link fence that didn't have barbed wire on it.
Thankfully this has woken up at least someone with some power in Arizona who now questions the ability of MTC to operate a facility; DOC director Chuck Ryan. After stating he lacked confidence in MTC's ability to secure the facility, he removed a lot of medium- and higher-security inmates from the facility, and says he wants MTC to prove to him that the state of Arizona shouldn't cancel its contract with the company.
