Hinckley is now calling on the hotel to stop holding events there "because bad things keep happening" and "it's just not a secure place to hold big events."

To illustrate his point, Hinckley described what happened back in '81 when he showed up at the hotel to shoot Reagan. He said back then, the security was "lax" too ... because he was able to sneak into a crowd of reporters waiting outside the hotel for Reagan to exit after delivering a speech. He said Secret Service agents never checked whether he was a reporter during their sweeps.
