So everyone is clear, this is not the person interview with the gun outside. This person was arrested in the building, after it had been closed by security, and was picked up by the Secret Service carrying a small knife. His car outside was then searched and they found an unregistered, loaded gun, for which he was arrested. The bomb sniffing dog detail scented on the car, and it was towed for further testing. The person with the legal, registered, loaded gun protesting outside was not arrested, although I am sure the Secret Service would prefer people not exercise their right to bear arms in the vicinity of the President.
I'm sure they would. I'd prefer the Secret Service remember whom they guy they work for, works for.
