In Texas, it’d be open season.
..........lol, except for a few parts of Austin, cops and pols around Texas would not dream of telling an entire major city to stay locked up in their houses, hiding under the bed for one punk 19 year old kid................almost nobody would do it even if it was ORDERED!
to be sure, thousands of guys/gals that would normally leave their guns at home would have them on their front seat and within reach but business would go on...............
