Call me paranoid, but...
These shooting incidents seem to happen with an almost artificial regularity. This guy was clearly 'confused'...and quite visible about it.
He is one of many that exist 'out there'.
I sometimes find myself wondering if the anti-gun crowd doesn't keep a few of these nuts on a string all the time...and 'turn one loose' with some extra nudging when things have been quiet for too long.
Since this one didn't commit suicide immediately affter the shooting, perhaps we can learn something from him...about the 50 year-old guy that Sheriff Dupnik is looking for.
