I'm putting my theory here for posterity:

The heart attack itself was the staged event. Hamlin is a freemason and is an actor who is in on the deception. His mural communicates that. He is fine, and they are deliberately presenting him as possibly already dead. That way, after the Super Bowl, he can give an interview on the Today Show or somewhere and be totally fine. Then, the media will all get to say, "Can you believe those crazy conspiracy theorists? By the way, they also are the ones saying the vaccines are killing people. Don't listen to them."

I strongly suspect this is what is happening and that many on this board are in the process of being successfully gaslighted.
