President Trump on Monday (May 15th) honored police officers who'd been killed in the line of duty, and vowed in an appearance before the annual National Peace Officers' Memorial Service in Washington to work to reduce violence against police. Trump said in front of an audience that included families of officers who'd died, "Every drop of blood spilled from our heroes in blue is a wound inflicted upon the whole country. And every heartache known by your families in law enforcement is a sorrow shared by the entire family of the American nation."
