In his Facebook profile photo, Dallas shooter Micah Xavier Johnson wore a purple, yellow and gold dashiki and thrust his fist into the air. His cover photo displayed the red, black and green stripes of the Pan-African flag.
He had joined several groups that made allusions to the Black Panther Party, including a group called the Huey P. Newton Gun Club, named for the black power group's co-founder.
The group, which was founded last year to oppose police brutality, teaches its members self-defense and conducts what it calls "armed patrols" through neighborhoods where the police have killed black men.
"We'd never seen him and we don't know him," said member Erick Khafre by phone. "The gun club isn't affiliated with him in any way."
Last week, Johnson shared a video of pilot whales being killed in the shallow waters off the Faroe Islands.
"Look at the joy on their faces," Johnson wrote. "Why do so many whites (not all) enjoy killing and participating in the death of innocent beings?"
He continued: "The church members and regular citizens (offspring of terrorist invaders) who stood around watching, cheering, eating food with their families while watching one of our ancestors be beaten, noose tied around their neck, hung up high for all to see ... then they all stand around and smile while their picture is taken with a hung, burned and brutalized black person."
