Lessons learned: Paris changes tack in 'yellow vest' riot controlA stone's throw from the Champs-Elysees avenue in Paris on Friday, cyclists were being put on notice by municipal workers.

The notice is part of a more proactive response promised by officials to contain rioting or looting during a fourth wave of "yellow vest" anti-government protests set for Saturday.
