The K-9 officer watches Cole walk into the room and they speak for about 3 seconds, after which the officer turns and walks away. Within a second Cole is out the door holding a shotgun and having multiple knives on his person. He's through the metal detector within 2 seconds.

It is impossible that that officer did not see Cole holding a long gun. It is not possible that officer didn't notice the multiple knives on Cole's person.

After Cole made it past the security, he was apprehended without a single injury/gun shot wound. You're telling me a man running towards a room containing the majority of the Presidential line of succession with a long gun somehow wasn't dropped on the spot? People have been shot on the WH grounds for far less than that.

Throw in Trump's complete indifference to the sound of the shooting, the slow response to remove Trump and others from the room and the jovial, all smiles demeanor of folks at the press conference after the "assassination attempt" and there's no way one could believe it was a legitimate threat to anyone's life.
