A soldier remembers Tim Hetherington

Anchor Lisa Mullins speaks with former US Army Sergeant Brendan O'Byrne (pictured) about war photographer Tim Hetherington who was killed in Libya on Wednesday. Hetherington is perhaps best remembered as director of the 2010 Afghan war documentary, 'Restrepo' about a platoon serving in a remote outpost in Afghanistan. O'Byrne was a member of that platoon.
