I have known quite a few vietnam combat vets.
Most were okay.... SOBER! Add alcohol or pills and then it is another story.
One of them committed suicide, just couldn’t live with himself anymore, when he drank he had the urge to want and pull a knife, that’s why he didn’t carry one.
PTSD is real,coupled with depression or some other disorder as bi-polar and it can be a disaster waiting to happen.
I am not justifying what this guy did by no means but if you watch him in the video, you can tell his experienced combat training took over for a short while
It is an injury... from being put in a position that some people just can not tolerate. Consider how outrageous it would be to give the victim of a rape, "Post Coitus Detachment Disorder". I don't agree with many things about President Bush, but this one, I feel he is right. Post Traumatic Stress or all the names it has had over the years... is an debilitating injury.
