Home town area, God bless him and you guys are right, level headed, did what needed to done, no need to hang his head in shame, I hope counseling does not give him a guilt complex, shooting or killing another, is tough, but if you know your in the right, like this, kid, it should be " man tried to kill me, I did not let him " end of story. No guilt, maybe and I mean maybe, sorrow.
None of us want to be in his situation, but we hope we do as well, if confronted.
