“President Obama on Monday announced a ban on solitary confinement for juvenile offenders in the federal prison system, saying the practice is overused and has the potential for devastating psychological consequences.

“In an op-ed that appears in Tuesday editions of The Washington Post, the president outlines a series of executive actions that also prohibit federal correction officials from punishing prisoners who commit “low-level infractions” with solitary confinement. The new rules also call for expanding treatment for mentally ill prisoners.

“The president’s reforms are expected to affect about 10,000 inmates.”
