Idiot. A prime example of one who needs his gun rights removed by judicial action. He's proven beyond any reasonable doubt that he's not mature enough to carry. Maybe a little time and a fine.
The line cutter should be publicly flogged for being an *******.
His mama should be slapped for not teaching him any manners. Maybe the mom of the cutter and the mom of the dumb ass should be sentenced to slapping each other once an hour from the hours of 5 AM until 9 PM. Maybe the Dad's should have a similar punishment.
