By laeffe (the new channel of Feltrinelli) and LA7, four documentaries filmed by Michael Mann, the director of Collateral and Public Enemies - Witness: Juarez, Witness: Libya, Witness: Rio, Witness: Sudan

Drugs, poverty, violence, corruption, arms trafficking and ethnic war have created some of the most dangerous hot spots on the planet. Witness follows the new generation of photojournalists in conflict areas in Mexico, Libya, Brazil, Sudan. What makes a journalist go closer to the action when everyone else is looking for shelter?

Witness: Libya

Michael Christopher Brown went to Libya five times during the conflict that led to the deposition of Gaddafi. With the revolution now over but the situation very delicate due to constant infighting, Brown returns to Libya after his previous trip with photojournalists Tim Hetherington and Chris Hondros. He remembers the feeling in Misrata: "The city was like a shooting gallery that day". That day, an exploding mortar killed Tim Hetherington and Chris Hondros and wounded Brown.
