I don't know if the second part has been discussed yet, but it's only possible with the former in place, so it makes sense to just ram that in first.

Most people don't care about this at all because they cannot fathom what it actually means. It takes the government actually turning on you to understand at a visceral level and by then it's too late. It seems there have still not been enough historical examples of this to truly burn it into memory.
