Somehow, I suspect that many of the veterans of combat WWI, WWII, Korea, and Viet Nam also suffered from PTSD, but I don't think that many of them caused any blood baths. It is just a bureaucratic trick to make sure that military veterans (originally identifed by Janet's Dept. of Homeland Security as potential Right-Wing Terrorists) are unarmed so that they can be safely gathered up for "re-education" a few years from now.
Governments are about the acquisition, extention, and exercise of power by an elite, who will then use that power to rule a peasantry for fun and profit.
Sauron lives, and his orc minions are on the march.
