I won’t believe this article because it says he carried a rifle.
WRONG
Remington 870 is NOT a rifle.
I don’t know much about guns and I believe every law abiding citizen that is in their right minds should be able to arm themselves, HOWEVER, I think there should be some sort of review on how weapons are sold online. And I think there is nothing wrong with crimminal checks and waiting periods so that crimminals and weirdos will be deterred.
