Secret Service fatally shoots armed suspect at White House checkpoint

At one of the most fortified addresses in the world, violence arrived swiftly on a Sunday when a suspect opened fire on Secret Service officers guarding a White House checkpoint. The officers returned fire, killing the attacker — but the moment left a second wound unaccounted for, a bystander struck by a bullet whose origin remains unknown. In the silence that follows such eruptions, investigators now face the careful work of reconstructing seconds that will carry consequences far beyond the checkpoint itself.
