On Monday, as prosecutors and defense lawyers delivered their closing statements in the case of the fatal shooting of 25-year-old Ahmaud Arbery in Georgia, black armed militias gathered outside the Georgia courthouse to march, with one notorious group issuing a warning.

"Ya'll are in serious trouble because the wrath of karma is coming on America," said a man who identified himself as the supreme commander of the New Black Panther militia. "We're not taking it no more."

Dozens of members of BLM 757, Lion of Judah Armed Forces, and the New Black Panther Party marched outside the Glynn County Courthouse to demand justice.

The Southern Poverty Law Center has described the New Black Panther Party as "a virulently racist and antisemitic organization whose leaders have encouraged violence against whites, Jews and law enforcement officers."

Three men are currently on trial for the killing of Arbery, Travis McMichael, 35; his father, Greg McMichael, 65; and William "Roddie" Bryan. They are facing charges that include murder, aggravated assault, and false imprisonment. Arbery, who was unarmed, was fatally shot in Satilla Shoes, Georgia on February 23, 2020.

A video from BLM 757 shows the march wheeling a coffin  down the street with a dummy inside it, inscribed with the names of black people who died at the hands of white people.

"We're standing in solidarity with the family of Ahmaud Arbery and for all those black lives that have been lost," one of the rally's organizers, BLM 757 President Japharii Jones, told Fox News.

"The message is we won't tolerate black and browns being murdered anymore, and we will pull up anywhere in the nation," he continued.

Jones noted that the groups have a shared goal of promoting self defense amongst black people.

"Our longterm plan is to arm our entire community with responsible gun ownership," he said. "We will be holding classes in the future and we will be setting up workshops in all 50 states."

Jones had no comment when asked how the groups would respond to a not guilty verdict.

According to Fox News, "In closing statements, prosecutor Lind Dunikoski argued that the defendants pursued Arbery in pickup trucks for five minutes through the neighborhood Feb. 23, 2020, and shot him because he was a Black man who refused to talk to them."

The defense stated that the McMichaels suspected Arbery had committed a crime, and were attempting to detain him until police arrived. Travis McMichael testified last week that he opened fire only after Arbery attacked him and grabbed his shotgun.
