Protestors are expected to descend on the Montgomery State Capitol today to demand justice for 39-year-old Stephen Perkins, who was killed by a Decatur police officer on Sept. 29.

Organizers, including Perkins’ niece Brooklyn Gaiter, a student at Alabama State University, are specifically asking the Alabama Law Enforcement Agency to release the body camera footage of the shooting and provide a fair and transparent investigation.

“Today peaceful protesters want justice for Steve Perkins. ALEA has been investigating for three weeks now without any arrest or updates on the case. Protesters want officers and the tow truck driver arrested, terminated and prosecuted for Perkins’ murder,” Gaiter said. “It will be a very peaceful protest, but we will be making our point as well to get justice for him and to release the body cam, because if we didn’t have the ring camera, we wouldn’t have anything.”

On the night of the shooting, the police said, officers went to Perkins’ home sometime after 1:30 a.m. on Sept. 29. Earlier that night, police said in a news release, Perkins had threatened a tow truck driver attempting to repossess his vehicle. The tow truck driver left, but returned with police. In the news release, police said that Perkins pointed a gun at one of them during the incident.

Home security camera video captured by a neighbor suggests that Perkins was not aware of police presence as he came into his yard that night. The footage showed that a police officer started shooting at him immediately after shouting for Perkins to get on the ground.

The city denied a public records request from AL.com seeking the bodycam footage as well as the officer’s personnel and disciplinary records. The officer’s name has not been made public. Police said the officer was on administrative leave.

This week, one of Perkins’ lawyers was denied access to the footage by ALEA. The law enforcement agency said the attorney needs to fill out a form first before it considers allowing the viewing of the video, attorney Cannon Lambert, Sr., told AL.com

Daily protests have taken place in Decatur since the shooting, leading to a number of arrests. Protest organizer Briona Watkins said she counted eight arrests for disorderly conduct during the weekend of Oct. 6, including one for cursing and others for stepping into the street, rather than remaining on sidewalks.

Gaiter said she’s heard from student groups at Tuskegee and Alabama State universities who plan to attend, and has also been in touch with organizers who have chartered buses from different parts of the state to take part in the protest.
