oooh, that stinks for her!
I meet so many people, many to the tenth power, tons and tons ( who own/carry guns ) - who can't seem to understand they need to actually study and know deadly force rules/laws for the jurisdiction where they live and visit. I suspect she thought having a ccw gave her police powers.
I think that a life sentence is too harsh - I would have given her ten or something.
Lots of people get shorter sentences for longer crimes.
I'm not buying the confused poor old man narrative, I think he was on something and he thought he would win the fight with the girl because he has won lots of fights with angry girls .
I hope whoever filled her head with nonsense about the who/what/where/why and hows of using a gun is questioning their advice.
