Open carry of assault rifle at political rally where nobody else is

From what I've heard he wasn't the only person there openly armed. The others were open
carrying sidearms.

While Arizona does allow private ownership of a class 3 firearm, it is not clear he was
carrying a machinegun. I really dislike the term assault rifle used for a semi auto.
