PARIS: Tens of thousands of protesters marched across France Saturday to denounce a security bill critics say would restrict the filming of police and posting images to social media, notably to document cases of police brutality. Thousands marched in Paris and cities across France, many of them angry about they say was the "disproportionate" response by police when they broke up an illegal New Year's rave in Brittany that attracted some 2,400 people. Estimates of the turnout varied widely between the authorities and the activists: while police put the total turnout across the country at 34,000, organisers insisted it was closer to 200,000. In Paris, the marchers came out despite a rare snowfall, carrying banners with slogans such as "Police everywhere, justice nowhere", and "State of emergency, police state."
