people have been doing that for a long time, but the level of urgency from the system hasn’t been at this level.
The shit has hit the fan about a decade ago already and not calming down at all, but intelligence gathering capability of secret services of all EU countries are being continiously degraded, because everything is E2E by default and money flows are obscured too.
Nobody likes to see shit being on fire and having all the dashboards down.
Another happening happens, the services are asked why they didn't prevent it or report it being likely -- what do they answer? "We can't read the damn messages, so we can't know if there is a cell that plans to do it again".
This is their best chance for them to enact mass surveillance, before the hoi polloi crack and finally get out of their couches.
