There you go again, making assumptions. Dude, I know many men who served in the Middle East wars of late.
Some of them came home, hit the turf a runnin', blended back into civilian life, became an instant leader, and made an instant favorable impression on everyone. While I've known some others who were so affected by their combat experiences in negative ways, that they immediately fell into drugs, alcohol, depression, personality disorders such as PTSD, and depression.
And for some of these ex-service men coming home, guns are about the worst thing they could have in their personal possession.
And I'm thinking this was the case for my friend, because I know he would still be here with us today, had he not had a gun in his possession.
