I thought the open carry laws did not require a permit at all? Just the basic legal rights to have a weapon in the first place ie no felonies, etc.
As far as legal concealed carry that is not really the issue here, unless you "flaunt it" which I guess is your right as well. As I understand this issue there was a guy carrying an assault rifle (M-16 type weapon?), "open carry", no permit required. At a Presidential type rally, as a "protest" of some kind, I guess! I gotta wonder though, how stupid is THAT!
