It is quite amazing that a site like this would have so many ignorant post from what should be smart posters.
Firearm laws vary from state to state. What might be illegal in one state may be perfectly legal in others.
Same with self defense and protection of property laws. If more people open carried in states where it is legal to do so as it was for this man in Texas, the populace would become more accustomed to it.
As the old saying goes,”use it or lose it”!
