> The real scandal here is why the French authority is making such request on an activist, why Interpol processed it (as far as I understand there are no crimes in play here?), and why the Swiss authority recognizes the request?
This seems easy to answer - according to French media[1], they were activists illegally occupying[2] buildings to protest rising real estate prices. This is illegal in Switzerland, too. What's the scandal? Authorities using their powers?
Illegal, okay, but is it a crime? I mean, after WWII interpol asked countries to not fill requests on nazis criminals because they did crimes of political nature and interpol needs to stay politically neutral [0].
But now, for an anti-capitalist activist it's not political?
