It's been 10 years since the attack on a very French institution: the targeting of satirical weekly Charlie Hebdo and the murder of 12 people, including five cartoonists and two police officers. That attack would launch a wave of jihadist terror on French soil and spark a slogan that would go global. 

In 2025, what does it mean to post "Je suis Charlie" - I am Charlie? How has that slogan evolved since that massive demonstration in Paris, four days after the Charlie Hebdo attack, where some 40 world leaders attended and where in a very rare moment of national unity, crowds even cheered the police?
