An order service of "yellow vests", white armband around the arm, Saturday ensured, for the first time, the security of the Paris demonstration to try to avoid confrontations and "police violence".

"As in the movement of yellow vests, we are of all social classes." The clashes around the Arc de Triomphe tarnished the manifestation of Act 9, which had previously passed through Paris without incident, from Bercy to the Place de l'Etoile, under the watchful eye of brand new "white armbands". "I volunteered (for the service of order), we're a quarantine officially, but we're more with those who did not want to give their name," says Anthony, 30. "As in the movement of yellow vests, we are of all social classes, men, women ...", said this former paratrooper, red military beret on the head.

"The objective is that it does not heat up, we get a stamp, we may take things (shots and projectiles, ed) but it will prevent all other protesters take," said Bryan, an employee in the 36 years old building.
