The International Day of Remembrance for Fallen Police Officers is observed worldwide every March 7 to honor police officers who have lost their lives in the line of duty. Established by INTERPOL, this day recognizes the service and sacrifice of law enforcement personnel, with the first observance taking place in 2019. Common causes of line-of-duty deaths include firearm-related incidents, vehicle crashes, and physical assaults. On this day, flags are flown at half-staff at INTERPOL duty stations globally, and a social media campaign using the hashtag #FallenOfficers pays tribute to fallen officers. The observance is supported not only by INTERPOL but also by Europol and various national law enforcement agencies, although some countries have their own specific days of remembrance.
