The White House will not be breached. In fact, this concern is quite gay, and sounds like the girly wailing of a rejected woman. They plan for everything. Will some try to climb the fence and run towards the building, probably. Will they fire off fireworks, crude bombs, and throw projectiles? Yes. But that is not a breach. There are rapid response troops standing by under the White House and in nearby tunnels (there are miles of tunnels and weapon storage facilities under Washington, some from the Civil War.) No worries here. There are more than enough weapons and men to turn any attempted breach into a meat grinder. Just enjoy the show.
