Zelalem Kibret remembers the day: July 8, 2015. He was in a prison library reading a biography of Malcolm X, his own copy, when some guards called his name and handed him a piece of paper. The message: All charges against him were withdrawn. He was being released.
"I was asking why," says Zelalem, a 29-year-old lawyer and blogger. "And nobody was giving us a reason."
