It should also cover concealed weapons!
The three judge panel which just ruled is bound by the precedent set in the Ninth Circuit by the Peruta decision which ruled that there is no right to concealed carry protected by the Second Amendment.
This more recent decision conforms with that decision.
What I find amusing is the realization that the anti-gun liberals will be begging for "shall-issue" concealed carry at such time as open carry is recognized as the protected right to bear arms. I, for one, will open carry EVERYWHERE as a means of coercing anti-gunners into removing their most onerous infringements.
If the anti-gunners want me to conceal my openly-carried firearm the price will include the ability to install a pistol-grip on any of my rifles. I will personally organize others to remove this and other infringements as the price for hiding our weapons. Otherwise, anti-gunners are going to think they are living in Dodge City.
