Firing weapons near a crowd - even in the air shows reckless disregard for your fellow human beings. Its irresponsible and idiotic.
Hey I did it all the time during marksmenship demonstrations

Its pretty much up to the local statutes I would thing and remember this is Texas not California or New York. Also isnt this ranch or farm country? I would think their pretty used to people firing guns off on their own property. An m-80 probably would have scared the protestors as much but may have gotten him in more trouble but I dont know the fireworks laws down there.

The worst part of this is how some of these far leftwing people are using this woman to advance their own agenda.
