Kentucky’s juvenile justice system has lingering problems with the use of force and isolation techniques and has done little to implement a 2017 state audit’s suggestions for improvement, according to a report released Wednesday. The new report from Kentucky Auditor Allison Ball says the state's juvenile detention centers lack clear policies concerning the use of isolation cells, Tasers and pepper spray, and have significant staffing problems. It also found that Department of Juvenile Justice staffers were using pepper spray at a rate nearly 74 times higher than it is used in adult federal prisons.
