One of the dumber statements you've ever said (and that's saying a lot).
How do you know you don't take someone there? Seems like Kyle did this with more than one person. Maybe he found it to be a good way for them to cope with the change back to civilian life?
I know the armchair experts on here think they know everything but it's certainly possible that handling a weapon again was a good way for someone coping with PTSD from battle to feel comfortable again. I'm certainly no expert like all the PhD psychologists on here.
Here are the symptoms of people with PTSD (which this man was known to have):
Irritability or anger
Overwhelming guilt or shame
Self-destructive behavior, such as drinking too much
Trouble sleeping
Being easily startled or frightened
Hearing or seeing things that aren't there
Would you hand a loaded gun to a person who was sleep deprived, self-destructive, delusional, and angry?
I sure as fck wouldn't!
