Calls for calm in Belfast as sectarian violence errupts

There have been violent protests in Belfast sparked by the annual marching season. This year Britain has sent in reinforcements and the White House has expressed concern. Alison Millar is a Northern Irish film director who looked at the Orange parade culture in a 2011 documentary called The Men who won't stop Marching. The riots this year, Alison told Helen Seeney, represent a turn for the worse.
