We've had a lot on our news in the UK about this case. We cannot see how this young man isn't doing serious time in prison for what would be an open and shut criminal act over here.
For myself as a very recent gun owner (I've owned guns since I was 18, and only gave them up very recently) I kept my muskets under tight control. It's what we do over here, and some unrest in the streets break out locally, my concern would be ensuring my guns were properly secure and ammunition kept away from said guns in case of break in. I would not be heading out as a vigilante looking to shoot people.
As a European I just cannot get my head around his thoughts other than he was a psychopath looking for a grand shootout.

The insanity has officially boiled over. Stop the world...I want to get off.
