This guy evidently never served abroad or in combat, he was stationed in New Mexico, and he was dishonorably discharged for domestic assault. I also don't believe it's Air Force personnel that suffer from the mental illnesses many others do.
The worst mass killings recently are either related to fundamental Muslim Terrorism or some sort of mental illness.
Orlando, San Bernadino, NYC last week, 9/11 were all Muslim Terrorism
The two church shootings, Newton CT, VA tech, LV, the CO school and theater shootings were all mentally deranged psychopaths.
What shooting was blamed on PTSD? maybe OR, I don't recall
I would also point out no generation experienced war more so than the greatest generation did in WWII, and these mass murders weren't a problem for them
Having said all that, I concur military members need our support for many reasons, I just don't see PTSD as being the reason for these senseless attacks
There is much greater access to the type of firearm used to carry out mass shootings now.
