Nah, it was normal black-bag police kidnapping bullshit. They released the kids later. It's not Nacht und Nebel tier, though it sure is headed that way.
This was a warning shot off the bow, essentially. Not even raising the stakes, just making the existing ones clear. "Know your place -- we can ruin you anytime." Showing that actually, consequences for using their fucked up hate-laws are not something that matters to them.
As for "what happens now"? Start pulling vulnerable people out of those fucking shitholes and sending them to safer places. Because they're GOING to go full Nazi. They haven't been hiding it for a long time now. So save the people who really need saving.
For everyone else, it's time to read about resistance movements in WW2 Italy, German-occupied nations, etc. Maybe throw in some Zapatista, Spanish Civil War, modern Palestinian resistance reading. Get real comfortable, extremely familiar with your history. Start figuring out how the real successful shit might look in a post-internet surveillance-world. You know, what-ifs.
