"Al Jazeera journalist Peter Greste remembers his time in prison in Egypt, where the government held him for broadcasting false news. "Prison anywhere is pretty tough experience. And Egyptian prisons are never the easiest. I was in two police cells before we actually entered the prison system. And I think the police cells were probably some of the toughest experiences of my life. One cell was a box about eight-foot square, and it had a toilet in one corner and a sink in the other and a door and a tiny little exhaust fan in the corner. There were 16 guys in that box. It was unbelievably crowded. It was impossibly, impossibly crowded. And there were a couple of guys who had been in there for about six months, with almost no time out of that at all. It was quite shocking."...."
