Los Angeles jail guards have frequently punched incarcerated people in the head and subjected them to a "humiliating" group strip-search where they were forced to wait undressed for hours, according to a new report from court-appointed monitors documenting a range of abuses. The Los Angeles sheriff's department (LASD), which oversees the largest local jail system in the country, appears to be routinely violating use-of-force policies, with supervisors failing to hold guards accountable and declining to provide information to the monitors tasked with reviewing the treatment of incarcerated people. The report, filed in federal court on Thursday, adds to a long string of scandals for the department. The monitors [were] first put in place in 2014 to settle a case involving beatings. The monitors, Robert Houston, a former corrections official, and Jeffrey Schwartz, a consultant, alleged that the use of "head shots", meaning punches to the head, had been "relatively unchanged in the last two years or more, and may be increasing". They also wrote that deputies who used force in violation of policy were at times sent to "remedial training" but that "actual discipline is seldom imposed." And supervisors who failed to document violations were also "not held accountable." The authors cited one incident in which a deputy approached a resident. "With no hesitation ... Deputy Y punched [him] 5-9 times in the head, and Deputy Z punched [him] 6-8 times in the head as they took [him] to the floor.
