Here’s how the ‘multi-layered protection’ at the White House correspondents’ dinner worked and how the hotel added security after Reagan was shot

The suspect detained after a shooting at the White House Correspondents’ Association dinner is believed to have made it past the outermost layer of security at the event at which President Donald Trump was scheduled to speak because he was a guest of the hotel, officials said Saturday.

The shooting suspect was identified as Cole Tomas Allen, 31, of Torrance, California, two law enforcement officials told the AP. Officials told reporters after the incident that Allen was armed with a shotgun, a handgun and multiple knives.
