IMHO...the only reasons to open carry a long gun is while transporting to or engaging in a hunt. Or, if there is open combat in a situation of rebellion against an oppressive dictatorship.
Such protests by a group of citizens against a group of citizens who dare think differently than the former, is not an appropriate venue for open carry of a long gun. It's like smoking a cigarette at a gas station.
If you’re afraid of a Riot, bring a Shotgun with the shortest Legal Barrel, 18.5 Inches.
Preferably with a Pistol Grip and a Collapsible Stock.
Also bring a Pistol as a backup weapon.
Screw it. When they beat you about the head and neck with their own weapons, or worse yet, they shoot YOU because you brought a protest sign to a gun fight, don't bother whining about it.
Beat me to it. It’s within your rights just indiscreet and inappropriate.
A pistol on your hip is appropriate for 99.99% of situations you are ever likely to need a gun. Hauling around a long arm is for soldiers, hunters, or the odd security guard. By the time Joe Average actually NEEDS to be packing that kind of heat in public we are in serious doo-doo.
