AUSTIN, Texas -- Relatives of the man killed in Saturday's overnight officer-involved shooting on Sixth Street dispute APD's version of the events. They say 24-year-old Landon Nobles never pointed his gun at police before he was shot and killed.

They say Nobles was out with friends and relatives to celebrate a birthday. After the bars closed, a fight broke out.

Video from the incident shows Nobles reaching into his shorts and casually flipping his shirt up. It appears he's showing people a gun. Moments later, you can hear the gunfire on video shot by bystanders.

"He was a great, young man and full of life," said Archie Kelly Jr., Nobles' uncle. "My heart goes out, especially to his two sons."

Austin Police said Nobles took off and pointed his gun at police, and they shot him.

Community activists said that may not be easy to prove through video since APD does not currently have body cameras for its officers. Austin NAACP President Nelson Linder said he's asked city leaders to invest in the technology for five years.

"We are in a very tough predicament right now," he said. "I would suggest again that they do this as fast as possible."

Sunday morning's incident is Austin's fifth officer-involved shooting of 2017. In 2016, the department experienced nine officer involved shootings. However, the previous decade averaged five incidents per year.

San Diego Police said--since they bought body cameras--officer-involved shootings have dropped 16 percent and citizen complaints are down almost 50 percent.

Linder believes a combination of factors has led to the decline.

"I think greater public scrutiny of officers' behavior, greater supervisor attention, but also they become more risk averse," Linder said.

A lawsuit has held up the City of Austin's plan to buy body cameras. The company with the lowest bid to outfit the police department sued the city after it did not win the contract.

Meanwhile, the two officers involved in the shooting -- a sergeant and corporal with a combined 25 years on the force -- are on paid administrative leave as the case is investigated.
