Nothing in the Second Amendment about concealed carry. The Supreme Court should decide that a citizen could open carry one musket - same as in 1776 - as the Founding Fathers could do.
No Bushmasters, no AK's, no military grade, no semiautomatics, etc. just one musket (flintlock, single shot).
You drugstore cowboys would be whining like little kids who had their lunch money taken away.
