To be honest with you, it's one of those things I'm kind of 50/50 about. I was in the Army and there are a few guys that were in my platoon I don't trust with firearms any more. As their ability to make sound judgement calls is apparently gone. PTSD or not, it is a condition, and some people that do suffer from it in a way that their sense of reality can be altered. Some of these guys are being medicated with all kinds of stuff I cannot even pronounce. I'm not about to tell you they need to own a gun, carry one or have access to one, period. Because some of them, they stop functioning like a normal person and go back into the zone or start flipping out at people. They don't need access to a gun because I don't think I can trust them to not let one fly at someone who looks like they might be from the middle east.
I know one guy god bless him we were on the same team together, took to drinking excessively. Like how excessive? like .412 BAC excessive. Pulled over with loaded .45 in the car. He's my best friend, but at that point, he's not making decisions properly. Why does he drink so much? Shitty PTSD, we saw a lot of dead people.
I knew another guy, basically leveled his Glock and threatened to kill himself right infront of my friend's wife and their 4 year old. I was also in the room. Drinking, guns, and PTSD. He wound up barricading himself in hosue with his gun and SWAT had to be called in. You can read about it here, I was the guy who called 911.

Mind you there are guys who have PTSD and function quite fine, it's not them I worry about. It's the guys who have some kind of psychosis or just can't leave Iraq in Iraq. The problem arises where people started using PTSD as some kind of blanket diagnosis. Call it PTSD or call it Bad Dream Syndrome, whatever you want. But for those guys who have this altered sense of reality. Maybe once they get over it and themselves, I'd understand, go for it. But some of those guys whom a legitimately f*** up from the floor up, they just don't need any more guns.
