My colleague Will Brown and I obtained dozens of photographs & video footage like this, that showed emaciated and dying men, underfed, beaten, suffering from heatstroke in prisons that were overflowing with sewage.
I witnessed the conditions in videocalls made with migrants who had been kept there for 8 months or so. Speaking the same language as those poor boys, made it really gutwrenching work. But it's why involving locals is best for our craft.
