I was barely ever home when I was 20.
I had college classes, a girlfriend and a gang of friends to go good off with every day.
My Mom never once called the cops because she hadn’t seen me in a few hours.
I suspect this is MOST Americans as well.
They knew he was a nut and he took off with a gun.
They knew something was up.
They also can be charged and certainly sued for
their actions.
