The two people in the beginning were discussing Wayne's cult. They do consider him a "terrorist" to national security and in typical Government intervention storming his compound and killing everything in sight in an effort to get him is what they were going to do. He's selling hugs, hoarding young Asian girls, and doing deals with politicians. He's on their radar and as I said, with their infinite wisdom after this rapture like event this was the idea they thought would be best. Similar raids of this kind have happened before. It's not farfetched.
They never referred to him as a terrorist. The government guy was mostly bemused by the group, and when a national security angle was presented to him, he seemed happy to use it as an excuse to knock around a bunch of quacks. They were described to him as a messianic fool and a bunch of dumb college students looking to get laid, with some weaponry lying around. The FBI had only been pursuing him over statutory rape charges. He almost flippantly greenlit the operation, because shutting down these amateurs seemed like no big deal in any form.
But my point is really, are we supposed to believe that the country has somehow changed so much over 3 years that a massively bloody shootout during a raid on a private compound doesn't register with the nation? Because if so, that hasn't been deomnstrated one bit. Maybe it's just poor storytelling, but I would expect something like that to be felt during the rest of the episode. The other characters reacting to news of something like this. Raids don't turn so violent and not become national conversations. We've certainly seen nothing in the show to establish that this would be an unremarkable event that the government and public both find ordinary and acceptable.
If the world has largely just moved on, then stick with that and treat extreme events appropriately. If the world has radically changed, show me that. The Leftovers is kinda sitting in the middle trying to have it every which way.
