Schrodinger's threat

The Better Beer Festival 2017 was canceled and it was revealed that the festival came under threat from extremist groups, according to authorities.

In response to this, I say, "Is that real? Can we actually see some evidence of the threat? Or is the threat under a box, trapped with a piece of radioactive material that has a 50% chance of killing it and thus since we cannot see what's going on inside the box, the threat is both real and imagined?"

...Yeah I'm going over to stand in a corner after coming up with that stupid joke.
