No no Starbrander - these guys are suffering post traumatic stress disorder.
Sadly we had a very distressing incident played out live on TV news yesterday. A Barrister (a lawyer who represents you in court - they are separate people here in Britain) who earned half a million pounds a year and was tipped to become a judge, suddenly snapped - shooting randomly out of his house in London, at Police and his neighbour - committed "suicide by Police" - they shot him dead at the scene. It turns out that he was a member of the Territorial Army (a reservist force) who's duties in Iraq had pushed him into a breakdown and although he left in 2002, he was suffering PTSD.
12,000 veterans is probably an underestimate, I suspect the figures are far higher.
