Go spend a few days or weeks sitting in the waiting rooms of a VA hospital to see Disabled Veterans. You better hope that they get treated for PTSD before they arm themselves and go on a shooting spree. Due to improved medical care for wounded soldiers, we're seeing a lot more TBI cases, as well.
There are a lot of Disabled Veterans who want to work, but can't get a job because businesses are afraid to hire someone who my get hurt or killed at a job site. They can't all work next to an exit, and the business could lose their insurance if they have people who can't leave a building on their own if there is a fire or other disaster.
I'm sure there are a few con men, but I've spent too many hours and days in VA hospitals to listen to your bullshit. A lot of con men who never served have tried to claim that all their records were lost, to get medical care.
