Panel’s security review suggests raising height of fence and getting an outside director to solidify president’s safety after Omar Gonzalez breached securityThe White House fence should be raised by up to five feet and new outside management brought in to shake up a failing security culture and prevent another intruder threatening the president, according to a damning report into the operations of the US Secret Service.The long-awaited conclusions of the independent review panel claim that the team of uniformed and non-uniformed officers in charge of guarding the president are undertrained and “starved of leadership”, warning they also risk killing harmless intruders if urgent measures are not taken to better secure the building’s perimeter.
