I asked a US Postal Inspector, if as with other Federal Law enforcement agents, they had to swear an oath to support and defend the Constitution.
He replied, "yes."
I Then asked him if that oath included my 2A rights?
I got no reply.
The entire concept of a sacred oath is meaningless after one has dispensed with the concept of a God that will hold you accountable to that oath.
Our public servants wish to be (and many already consider themselves) our civic masters.
What master wants his servant to possess arms that make his servants his equal?
