Rand Paul's 13 hour Filibuster

As your quote shows, the only way this is relevant is in extremely unlikely hypothetical examples which again is why it is precisely a non-vital issue.

An infinite number of extremely unlikely hypotheticals can very quickly snowball, just based on the sheer numbers involved. I've always been one to believe luck will always draw me the worst card, but if I'm given 100 chances to win a lottery that has a 1/100 chance of winning, I'd say my chances in that situation would be better than if I had only 1 shot at it. It's not unlikely precisely because of how vague it is; it can apply to absolutely anything. Man brushing his teeth on the way to work? Toothpaste is considered a bomb material at airports or some pomegranate, take that fucker out. Woman handing her son a glass of water? THAT PSYCHOTIC peach IS TRYING TO DROWN THAT LITTLE BOY, TAKE HER OUT.

There are literally an infinite number of situations that can be construed by an outsider as "a threat", even "a threat to national security". Especially when the outsider in question is a paranoid/delusional whose only electable quality is that he had charisma (charisma that happened to be based entirely on lies, but charisma nonetheless) 5 years ago.
