“Nous sommes tous Charlie,” chanted the million-strong crowd marching through the City of Light yesterday in France’s largest demonstration ever, as more details about the perpetrators of the Charlie Hebdo massacre came out. The kosher market attacker had been in the U.S. terror database. And the wife of one of the newspaper shooters expressed her horror and sympathy. France deployed 10,000 soldiers across the country in a bid to thwart terror. Meanwhile, White House expressed regret for not sending a high-ranking official to the unity rally.
