I read CNN are questioning the assessment of wartime time veterans stress (as a defense for murder).
It is hard to imagine any war where dissociative phenomena are not going to be a major factor for all those involved.
I have seen former soldiers brought before the courts charged with engaging in minor sex acts (exposure) though to more violent acts, in which the defence solicitors make the same claims in mitigation: PTSD.
It is a hard call for society to demand that individuals so aggressively rip up the rule book for a short space of time and then expect them to fit right back into the rules without assistance.
Some people might well be more susceptible to than others. Predicting those and deselecting them from the military (or at least front-line) occupations might be a social step forward for all except all-out-war. The current economic situation seems to pay for bombs but not effective rehabilitation. Which I wonder, is the best way forward?
A suggestion from a US doctor is that returning soldiers have access to a buddy system to help alert and support. A very good idea that might just help keep some from offending.
That said the DSM IV (or V, if using the beta version) is as accurate at diagnosing the myriad of conditions that arise. Functional scanning is also highly supportive of the observations and clinical reporting.
