Nine police officers from France’s riot squad are standing trial in Paris, accused of beating peaceful "yellow vest" protesters in 2018. Prosecutors say the CRS officers entered a Burger King restaurant where people were hiding from tear gas and repeatedly struck demonstrators who were not acting aggressively. The officers face charges of aggravated intentional violence. If convicted, they could face prison time and heavy fines. The defense argues the officers were working under extreme stress during a day of violent riots that left hundreds of people injured or under arrest.
