The Constitution doesn't address whether the right to bear arms is either open or concealed carry. The Constitution does not grant this right - it, among others, is considered a natural right, applicable to the free people. It only lists this right, among others, to emphasize that government is not supposed to infringe upon it. We all see how poorly that enumerated philosophy is followed, understood, accepted, or defended.

The Constitution mandates that people have the right to bear arms; it doesn't specify about concealed carry or open carry. Yet I, as a Californian, can do neither. Open carry is illegal in California, and only a small few can get a concealed carry permit (varies by county). It is very clear that Californians' constitutional rights are being "infringed".

It's hard to argue that "bear arms" means something other than "carry a gun".

I don't think open vs. concealed matters in this context. It's probably even easier to "play a cop" with open carry.

Only if you some how believe that carrying a concealed weapon isn't bearing arms.

I think that depends on your view.

There is no constitutional right for the concealed carry of a gun, based on your view of what the second amendment means.
