What has gone wrong in America? The White House Correspondents' Dinner descended into chaos on Saturday after a suspect armed with multiple guns and knives charged past security in an apparent attempt to reach US President Donald Trump. This has raised serious questions about the president's security detail, though the larger question remains about the motivations of the suspect, Cole Thomas Allen, a 31-year-old tutor from California. What were his intentions? What's fueling this apparent new normal of political violence in America? What may be the knock-on effects for the wider world?
