Michael -
I'm curious as to where you believe the line exists. I'm not sure I agree that "arms" includes Javelins, Apaches, and JDAMs, but I also believe that there is nothing wrong with citizens owning and freely transferring machineguns. Where I have difficulty is articulating where the limits are.
I would define that line in a fashion that is similar to how I would describe pornography; It's tough to define but I know it when I see it.
For instance, I agree that there's nothing wrong with owning a full-auto.
However I have strong reservations about a citizen owning a tank or an ICBM.
I also believe that open vs. concealed carry is not an infringement and should be decided by individual states.
I believe that prohibition of carry on public buildings or grounds, with the exception of prisons is an infringement.
I certainly believe that prohibition of carry of all types is an infringement.
So, where the definition of the line lies is certainly up for debate IMO.
