You might want to add Shin Dong-hyuk's first-hand account of life in a North Korean prison camp. Slavery, starvation, torture, rape, and murder are the norm, and given that it's illegal to be related to someone in prison, a ridiculous percentage of the country's population is enslaved in these prisons. The DPRK's human rights violations go well beyond the oft-cited starvation of the populace.
