About International Day Against Police Brutality

International Day Against Police Brutality is observed on March 15 and has been marked through civil-society actions since 1997.

The Montreal-based Collective Opposed to Police Brutality (COBP) says the first day was organized jointly with the Black Flag Collective in Switzerland.

Why International Day Against Police Brutality matters

The observance is an activist/civil-society day focused on concerns about police violence, accountability and rights.

Its origin is documented by organizers; claims about the incident that inspired the date are presented as organizer-attributed history rather than as an independent legal finding.

History of International Day Against Police Brutality

COBP states that it has organized an annual March 15 demonstration in Montreal since March 15, 1997.

A 2007 movement publication says the first international day was initiated in 1997 by the Black Flag Collective in Switzerland with help from COBP in Montreal.

That publication says March 15 was selected because of a March 15, 1996 incident in Switzerland involving two children and police.

Current Montreal organizers continue to describe the 1997 COBP/Black Flag launch as the origin of the March 15 tradition.
