i posted this somewhere else, and i'll copy it here.....
why was he arrested for that? it's not illegal. you are free to open carry in Alabama without a permit. now, if he had it concealed and didn't have a conceal carry permit, then, yes, THAT is illegal. but i will reserve judgement until the facts come out.
but i'd like to add: according to the report, he was arrested by the University of Alabama police. and their policy doesn't allow you to carry a firearm while on campus or any property leased, owned, or controlled by The University.
if he was indeed on campus, then he isn't allowed to carry at all (which i do not agree with, by the way).
