Dallas Police Chief David Brown told a television audience on CNN's "State of the Union" that Micah Johnson, the gunman in the deadly Dallas shootings, spent his last hours of life laughing, singing and taunting police about how many he had shot and killed.
Brown also said that after officers sent in a bomb-equipped robot by remote-control to stop Johnson's killing spree, they found a message written in blood containing markings and the letters "RB," the Associated Press reported. Police are still puzzled by the markings and initials and don't know what they refer to, and are trying to piece together their meaning by scouring Johnson's house for clues, Brown said.

Brown also said Johnson taunted police for two-plus hours during the standoff, laughing and singing, and even asking at one point how many officers he had shot.

Meanwhile, information emerged in recent days of Johnson's interest in groups and websites that were focused on exposing perceived injustices in the black community. As CNN reported, Johnson's Internet history showed he not only visited sites dedicated to the Black Lives Matter movement, the New Black Panthers, the Nation of Islam and the Black Riders Liberation Party – the last two, being labeled hate groups by the Southern Poverty Law Center – but he also "liked" several of the sites on his Facebook page.
For instance, Johnson "liked" the African American Defense League, a group that put out on its Facebook page, shortly after news broke of the police shooting of Philando Castile – the Minneapolis man who was pulled over by an officer for a broken tail light, and who then was fatally shot – that it was time to act.

The AADL's Facebook post was blunt. It read: "The Pig has shot and killed Alton Sterling in Baton Rouge, Louisiana!: You and I know what we must do and I don't mean marching, making alot of noise or attending conventions. We must 'Rally the Troops!' It is time to visit Louisiana and hold a barbeque. The highlight of our occasion will be to sprinkle Pigs Blood."
The AADL's site also contained a message last week "calling on the gangs across the nation! Attack everything in blue," CNN reported. That message was quickly deleted, however.
