Following the death of three law enforcement officers in Baton Rouge, La., on Sunday, President Obama said that "attacks on police are an attack on all of us."
Three officers were killed and three others were wounded in an encounter that began shortly before 9 a.m. Sunday. Louisiana law enforcement said they believe the gunman who shot at officers was killed at the scene. A law enforcement source confirmed to NPR the identity of the shooter as Gavin Eugene Long. The 29-year-old black man was a former Marine who served from August 2008 to August 2010.
