Arizona, where I reside, still has many 'old west' type laws. Being able to carry open firearms anywhere except bars is one of them. So this was perfectly legal and since they were outside, where the president was not, the secret service didn't care.
1. They would never let them inside the same building with the President.
2. If the President was outside speaking those individuals would have been asked to leave or hand them over, peacefully and quietly.
