About two hours before the gunman opened fire in Las Vegas BIG & Rich had just finished their set and were heading over to John's bar, Redneck Rivera near the venue.
When an off-duty officer heard the shots he walked up to John, flashed his badge and said "for the first time in my life I'm unarmed, are you?"
John carrying his concealed weapons permit responded "Yes sir, I am"
The officer asked to use his weapon to protect the bar.
