New Video Showing Alec McKinney being confronted by a security guard

This video shows Alec pointing a gun at his head, as if to kill himself, then being confronted by a security guard and getting on the ground.

The security guard said that Alec repeatedly said "Kill me, kill me, kill me, I don't deserve to live" as well as responding to the security guards question of how many shooters were there by saying "We have more guns than you, they're gonna kill you, you need to kill me" before talking more about the voices by saying "They are saying to kill me, kill me" and "They want you to kill me and I want you to kill me".
