Well, just to provide a technological angle... When the protests started hitting the airport, police started asking for boarding passes so that only passengers could enter. Then, the protesters set up a Telegram group to share actual boarding passes from today's flights. Dozens of them were posted to the group. Apparently the ruse worked, although from what I've heard, not for long. The police started matching the passes with IDs.
