 There should have been an emergency frequent comms channel that they could have said, we have a shooter on the roof, shooter on the roof. Secret Service should have rushed the stage and immediately took the president and took him off and then responded to the counter sniper. The shot should not have gone off. That is the failure in itself. You're supposed to be able to try. The best security is when you go in and you're actually able to prevent an incident, not react to an incident.
