Flags Again At Half-Staff For Victims Of A Mass ShootingPosted by John AxtellDate: March 24, 2021198 Views Flags across the country are once again flying at half-staff to honor and remember the victims of a mass shooting. Monday, just hours before a multi-day period of flags at half-staff for last week’s killings in the Atlanta area ended, a lone-gunman with an assault rifle killed 10 people including a police officer in a supermarket in Boulder, Colo. Under the proclamations from President Joe Biden and the nation’s governors, all U-S and state flags will remain at half-staff until sunset on Saturday.
