Except the guy was working for the DCRI, which has turned into the DGSI since 2014. So it has been out of the police forces for at least 10 years. Not a few weeks ago.
You can find a lot of information on french media, like https://www.leparisien.fr/faits-divers/reseau-franc-macon-de...
What would be more concerning is that current member of the DGSE were planning a murder (in the same article). But then again, they were arrested, and this is why we know what likely happened to Pasquali. This is not Russia where the FSB can run wild.
Finally, I do find it strange to argue with a brand new account who basically just post to defend Telegram.
