Body camera video, newly surfaced as part of a civil rights lawsuit, shows the moments when an East Bay Regional Park police officer used a Taser on an unarmed man who is now in a coma in a situation that started over expired car tags.

The video shows park police officer Jonathan Knea yelling at Deonte Charles Faison to "Get down!" and stop running after he began questioning about his expired tags on April 5 at the Martin Luther King Jr. Regional Shoreline in Oakland.

The suit was amended on Tuesday in U.S. District Court in Northern California and alleges that using a Taser in water violates basic officer training that says the tool must not be used when a person is located in water, mud or marsh.

"It naturally follows that any officer who intentionally uses a Taser on a person who is near and/or standing in water must be considered to be showing deliberate indifference for human life," wrote Adante Pointer, who is co-representing Faison.

The suit names Knea personally, the East Bay Regional Park District, and Alameda County, as a deputy sheriff arrived at the scene that day as well.

In court documents, attorneys Noah Blechman and John Swafford, who are representing Alameda County, denied all the allegations. When the suit was first filed in April, the park district and county officials did not want to comment because of potential litigation.

Park district spokesman Jason Traverso reiterated that on Tuesday, adding, "Our hearts go out to Mr. Faison and his family."
