It's been almost 50 years since the killings in Northern Ireland known as Bloody Sunday. Now, prosecutors will decide whether the 18 British soldiers involved, should be tried for murder. They could be accused of shooting dead 13 civil rights protesters in Londonderry in 1972. As Sarah Morice reports, there's a lot riding on the prosecutors' decision. #BloodySunday, #NortherIreland, #Britain
