Not so bad really
Here is a presentation, in French of course, it doesn't actually seem as bad as you might first imagine.
OCLCTIC
It's too long for me too translate but too resume things very briefly, there are 4 main sections.
1: International relations ( Strange she but she doesn't mention what this section actually does) Probably cooperation with CIA, GCHQ etc.
2: Operations : Taking care of the various web scams, false credit cards, piracy and mobile telephony scams ( automatic SMSs sent in the background to over-taxed tel. numbers etc).
3: Technical Assistance - Informing the public about dangers, setting up stategy for safe usage etc. A kind of hotline.
4: Tracking illegal web content - Paedophilia, Racism, Terrorism etc ... They have a website in which you can notify them of URLs/Sites that contain illicit content.
They appear to be a mix of both the police and the Gendarmerie and will and do follow up the various affairs. Doesn't look so bad really, this is not some government nanny squad, they actually do appear to be on the look out for the bad guys ( or at least in the video that's how the come across).
Les Francais sont loin d'etre aussi con que certain peut imaginer.
