A few hours after this year’s annual May Day march in Paris, hundreds of student protesters gathered at a small plaza in the Latin Quarter. Hoping to demonstrate against education reforms, they were quickly met by police violence.

In one incident — filmed by an activist from the left-wing party France Insoumise and shared widely on social media in the following days  — a group of riot police shove a peaceful protester to the ground before delivering countless blows with their clubs.

Except, it turns out not all of them were cops.
