No it is not....... the PTSD is the reason for their behavior, but never an excuse --they need to seek out some professional help for their problem.
I think violence is never acceptable.
That being said, it's understandable. It's just that being understandable and people knowing someone is suffering, shouldn't be an excuse to harm anyone.
No of course not. I have it too but one must learn to walk away. Let it go in public and anything is possible Death, jail, maimed, anything as you lose control and don't know what you are doing.
There's no excuse for random violence.
VIOLENT, it never works, it matters to not bee*****
Does it happen?...yup
