that atrocities are not the domain of any particular political or economic ideology or system, but rather a danger that we need to fight against actively everywhere, and now.
According to the BJS data sheet linked in grandparent, the leading causes of death in prison for 2016 are:
- Cancer (1,128)
- Heart Disease (1,025)
- All Other Illnesses (525)
- Liver Disease (260)
Cancer and Heart Disease are also the leading causes of death for people not in prison. I don't think this is at all convincing evidence of an "atrocity."
Taken as categories, 44% of people in prison die as a result of illness, 31% as a result of suicide. (both sourced from BJS still) Both avoidable with the right funding, and yes, atrocities. If we're going to have a justice system that lives up to what it claims, a side effect of a prison sentence shouldn't be death.
