The man accusing three Austin police officers of violating his civil rights was back on the stand in federal court Tuesday.

Ramon Hernandez was beaten and stun-gunned by police officers after a traffic stop in September 2005.

The six-woman jury in U.S. Magistrate Judge Robert Pitman's court viewed the video Tuesday.  As the use of force by the police officers escalated, some members of the jury grimaced. One juror held her hand to her mouth, while others simply sat and stared at the video screen. It shows him being held down face first by three officers and being struck by two while he is handcuffed.

In the dash-cam video, Hernandez can be heard screaming as the officers restrain him.

As the tape plays out, one of the officers can be heard telling Hernandez to "stop resisting."

Austin police Officer Christopher Gray, who delivered 14 punches to the back of a suspect who fled a car accident scene in 2005 in a beating captured by a patrol car video camera, testified today in a federal civil rights trial that his force was justified.

Gray said he punched Ramon Hernandez, 27, after he had been handcuffed behind a Central Austin transmission shop because he was fearful Hernandez would turn over and attack him or his fellow officers.

"You felt threatened?," asked Hernandez's lawyer, Amber Vasquez Bode.
"Yes, ma'am," Gray said.
"Was it because he was face down on his belly?"
"No, ma'am."
Gray said "it's the totality of the circumstances," explaining that he had witnessed Hernandez earlier putting his hands on then-Officer William Bradley Heilman's gun.

Bode paused the video while it depicted Gray kneeling on top of Hernandez's midsection and asked whether Gray considered Hernandez under control.

After a slight head and hip movement by Hernandez, Gray unleashed a flurry of 10 punches.
Bode asked why Gray didn't stop punching after two or three or four or five punches.

"I stopped punching when he stopped resisting."

Later on the video, Gray is seen punching Hernandez twice more. After another pause, he punched Hernandez two more times.
