President Obama ordered flags on all public buildings across the country flown at half-staff to honor the five police officers who died and the seven others who were wounded during Thursday night’s sniper attack at the end of a police brutality protest in Dallas.

“As a mark of respect for the victims of the attack on police officers perpetrated on Thursday, July 7, 2016, in Dallas, Texas… I hereby order that the flag of the United States shall be flown at half-staff at the White House” and all public buildings and grounds, the president said in a proclamation Friday.
