Flags across the United States are lowered to half-mast today, May 15, in observance of Peace Officers Memorial Day, which honors law enforcement officers who have lost their lives or been injured in the line of duty. This annual event is marked by a presidential proclamation, with President Donald Trump emphasizing the need to pay tribute to these brave individuals and support their families. The day is part of Police Week, first established by Congress in 1962, which includes various memorial ceremonies nationwide. In Nebraska, flags are also lowered to honor Staff Sergeant Robert A. Keuchel, a World War II airman from Omaha who was killed in 1945. His remains, which remained unidentified for decades, were confirmed in 2025 following excavations. A burial service for Keuchel is scheduled at Omaha National Cemetery, where flags will remain at half-staff until sunset. The protocol for lowering flags involves raising them to full staff before lowering them to half-mast, a solemn routine for moments of remembrance.
