The growing outrage in the US over solitary confinement

Between 80 thousand and 100 thousand prisoners across America are in solitary confinement at on any given day. Last month a former Black Panther, Albert Woodfox walked out of a jail in Louisiana on his 69th birthday after being held in solitary confinement for 43 years. Serving a sentence for armed robbery in the early 1970's he was then accused of killing a guard in prison; he was convicted twice and both cases were later overthrown - yet he remained in solitary confinement. Jean Casella is from US project Solitary Watch which aims to bring firsthand accounts, news, research and policies about solitary confinement into the public arena.
