For all we know there were some carrying and they got shot...
Yes that’s always possible too. Perhaps a mixture of concealed and open carry may be best possible deterant. Beyond this, it looks like we’re stuck with obama’s Bff Muslim invaders plus of course the occasional native guy who just loses it somehow. No amount of legislation or political bs speechifying or ev n policing can stop Muslim terrorists or a mental case of the domestic sort.
We just can pack and carry and keep alert and that’s maybe what is possible. Paradise is not in this world - at least not presently. Thanks
