Flags should be flown at half-staff from sunrise until sunset today in observance of Peace Officers Memorial Day. It honors federal, state and local officers killed or disabled in the line of duty. President Obama signed a proclamation ordering flags nationwide be lowered in observance of the somber celebration. Gov. Mike Pence also asks businesses and residents to lower their flags to half-staff to pay tribute to the brave men and women in law enforcement across the state and nation.
