The death of 'American Sniper'

The death of 'American Sniper', We know who killed celebrated US Navy Seal Chris Kyle and his friend, but do we know why they died?

In the US and beyond, the conversation sparked by the conviction of Eddie Ray Routh is about mental illness, PTSD and post-military support systems.

Defence lawyers for Routh said the 27 year old was psychotic at the time of the shootings. His family have repeatedly said he was suffering from post-traumatic stress disorder. But prosecutors disagreed.

On World Have Your Say we’ll hear from army veterans about life inside the military and after it. How common is mental illness among army vets, what forms does it take, and how much of a stigma is it? Does the army and society at large need a different approach to helping those who suffer from it ? Or is it sometimes used as an excuse to try and justify criminal behaviour?
