SAN DIEGO - For the first time since he had a gun pointed his way, the man involved in a confrontation with a San Diego police officer over a curfew sweep told his story to 10News.

"He just wanted to use his gun," said Hyland Stangl.

Cellphone video shows a San Diego police officer pointing a gun at Stangl on Saturday night.

Stangl was recording his friend being held down by a San Diego police officer after he refused to show his ID in a curfew sweep in front of the Rite Aid in Carmel Valley.

"He takes out his gun and pulls it out and points it at my face and keeps telling me to get back," said Stangl.

In the video, the officer says, "Get over there."

"You do not, you cannot point the gun at me for not doing jack****. That is bull****," a male voice is heard saying in the video.

The office says, "Get back over there."

"Put that gun away," a male voice says. "You're going to shoot me for not moving back?"

Garrett Paddock, 19, is seen in the video on the ground. He told 10News that one minute he was eating candy and the next he was face down on the blacktop.

"He was like, 'Drop your M&Ms, drop them, drop them,'" said Paddock. "Then I set them down and the next thing I know is I got slammed against the car. My shoe fell off and then I was on the ground."

A retired San Diego police officer told 10News the officer would be justified in drawing a gun if the officer felt threatened.

"It was 11:20 at night and the officer was investigating curfew violations," said San Diego police Lt. Andra Brown. "Age is the issue. All they had to do was show their IDs."

Paddock not only refused to show his ID and can be heard challenging the officer.

In the video, the officer says, "Give me your other hand.

Paddock is heard saying, "You guys have no probable cause to search us for any reason."

The officer says, "Shut your mouth."

A constitutional law professor at the University of San Diego told 10News that since the three men in this case looked like they may have been under the age of 18, the officer was justified in making them show their IDs.
