Harmon's niece Alisha Shaw pushed back against such claims.
Both police and the district attorney's office say Harmon threatened officers with a knife. Harmon then attempts to flee, and in the moments following, an officer fires several shots at his back.
The video seems to tell another story however, as Harmon can not be heard making that threat and never appeared to turn toward officers before he was shot.
He further claimed that this was the "scariest situation" he'd been in, ten years in law enforcement and two military deployments combined.
Investigators say that they found a knife on the ground.
This despite the fact that body cam footage clearly shows officer Clinton Fox shouting, "I'll fucking shoot you" before firing three bullets at Harmon's back as he tried to run in the opposite direction.
Recently released body camera footage shows Utah police fatally shooting a man from behind as he attempted to run away from officers, once again sparking tensions between the black community and police officers, and sparking accusations of racial profiling and police brutality. Be warned: both videos contain graphic images of violence and could prove disturbing to many viewers.
We all remember the fateful death of Walter Scott, captured on video for all to see.
Harmon is one of 748 people who have been killed in interactions with the police this year, according to data compiled by The Washington Post.
It's rare for police officers to be charged and even more rare for them to be convicted in such cases as law allows the use of lethal force if they perceive a threat. "It's just brutal. How could anyone with eyes and ears believe that that officer was justified?"
For weeks Harmon's family and a growing legion of supporters demanded that the video of his last moments be released. "He was only trying to get away", she added.
The Salt Lake City Police Department did not immediately respond to a request for comment from BuzzFeed News. "They don't care about black lives".
The footage from one of the body cameras shows Harmon groaning on the ground as he loses consciousness, losing blood as officers try to handcuff him and give him aid.
The D.A.'s office says that officer's use of deadly force was justified because the officer "reasonably believed deadly force was necessary to prevent death or serious bodily injury to himself and/or others". "Hey Patrick, stay with us".
In an email to members of the press late Wednesday evening, SLCPD representatives said Gill's decision prompted them to release the footage.
Jeanetta Williams, the president of the NAACP's Salt Lake City branch said that Rio Grande, the district where Harmon was killed, has been the subject of a recent effort to get a large homeless population off the streets and tamp down on issues like drug dealing.
