Everything they say, everything they do, and the history of the thousands of times they’ve done everything they can for this exact same reason. To believe otherwise is to reject every ounce of common sense and have a 3rd grade level, govt approved, cartoonish understanding of history… no disrespect. But it’s not even slightly well hidden. All you have to do is not take them at their clearly dishonest word that makes no sense anyway, and make a cursory investigation, imo.
I am with @TheGuySwann on that. The French government does not care about protecting citizens from criminal offenders. They want to stick their noses in your and my peer-to-peer conversations in order to consolidate their power and get closer to their goal of establishing a totalitarian government a la Louis XIV. But without Versailles. Unlike the sun king, they might not go back to not taking daily showers. Unless, of course, they seek inspiration from other totalitarian leaders like chairman Mao and decide that taking showers is for only for lowly plebs. https://www.grunge.com/181873/the-disgusting-truth-about-mao-zedongs-personal-hygiene/
