In the news...

(une) émeute = a riot

Word that you would find all over the headlines in France these days, after close to a week of non-stop riots in the suburbs of Paris, following the death of two teenagers who were fleeing the police.

A related word:
CRS = Compagnie Républicaine de Sécurité (Republican Security Squad), French riot police. When masculine, designates a member of the squad ("un CRS").
A famous chant of rioters taunting the CRS is: "CRS, S, S!" which manages to compare them to the German SS in barely 5 letters. I am sure tha,t unfortunately, we hear this one a lot these days.
On a side note, you do not want to mess with a CRS, if you ever meet any.
