From the NY Times:

A police officer in McKinney, Tex., who was seen on video pulling his gun on teenagers in swimsuits and shoving a young black girl’s face in the ground at a pool party has resigned, the police said Tuesday.

Cpl. David Eric Casebolt, who had been placed on administrative leave after the episode on Friday, remains under investigation, Chief Greg Conley said at a news conference. The corporal will keep his pension and benefits, the police chief said.

“Our policies, our training, our practice doesn’t support his actions,” Chief Conley said. “He came into the call out of control, and as the video shows was out of control during the incident.”

The video was taken on a cellphone and posted to YouTube, where it set off another in a recent series of debates involving race and police tactics. The police said Corporal Casebolt and other officers were responding to a call about a fight and a disturbance at a community pool in Craig Ranch, a racially diverse subdivision north of Dallas.

Corporal Casebolt can be heard shouting profanities at the teenagers, and officers handcuffed several who had followed his orders to sit on the ground. He appeared to grab the girl and pin her to the ground after she did not heed his orders to leave.

One adult man was arrested on charges of interfering with the duties of a police officer and evading arrest. Chief Conley said on Tuesday that those charges had been dismissed.

At the news conference, Mayor Brian Loughmiller said that officials recognized a need for better training for officers, but that there needed to be expectations for interactions with police.

Greg Willis, the district attorney for Collin County, said in a statement on Tuesday that his office had received numerous inquiries about the case.

“We share the public’s legitimate interest in a full and fair investigation of this matter,” he said. “We are currently awaiting the results of the McKinney Police Department’s investigation and ask for patience as their investigation continues.”
