Without wanting to diminish the very fair criticisms of the US penal system, it is not the same as a North Korean concentration camp.

During a day-long hearing held in Washington, DC in 2016, Chief Judge Navi Pillay and her fellow judges heard testimony from North Korean defectors, including a North Korean political prison guard and prison camp survivors. They provided graphic testimony of atrocities they witnessed or were subjected to in the political prisons, including accounts of:
prisoners tortured and killed on account of their religious affiliation, with officials instructed ‘to wipe out the seed of [Christian] reactionaries’;
a prisoner’s newborn baby, fed to guard dogs and killed;
an abortion induced by three men standing on a wooden plank placed on a pregnant prisoner’s stomach;
a female prisoner losing consciousness after enduring a beating designed to trigger premature labour, with prison officials killing her baby before she could regain consciousness;
a prisoner raped by a security officer, after which the officer pushed a wooden stick inside her vagina and beat her lower body, resulting in her death within a week;
the deliberate starvation, malnutrition, overwork and death of countless prisoners, including between 1,500–2,000 prisoners, mostly children, who are believed to have died each year from malnutrition in one camp alone, with many other prisoners beaten to death for failing to meet production quotas;
a soldier supervising a forced labour site rolling a log down a steep mountainside, killing ten prisoners as they were carrying logs up the mountain;
routine public executions of prisoners, carried out in front of both children and adults, designed to subdue the prison population;
the execution of starving prisoners found digging for edible plants on a mountainside; and
the beating to death of a prisoner for hiding stolen corn in his mouth.
