Policeman who pulled gun at Texas pool party resigns

A Texas police officer videotaped pulling a gun out at a teen pool party resigned in the latest racially-charged incident involving excessive force by US law enforcement.

McKinney Police Chief Greg Conley on Tuesday denounced Eric Casebolt's "indefensible" actions, insisting they did not reflect the department's "high standard of action."

Video filmed by one of the teens and later posted on YouTube shows Casebolt -- who is white -- shouting obscenities at the black teenagers as he orders them to lie on the ground.

At one point, he is seen throwing a bikini-clad young woman to the ground and pinning her down. He then pulled out his gun when two young black men approached, apparently trying to help her.

"Our policies, our training, our practice do not support his actions," the police chief said at a press conference.

"He came into the call out of control and as the video shows, was out of control during the incident."

Conley said a dozen officers were sent to the community center Friday amid reports of a "disturbance."

Authorities launched a probe after becoming aware of the existence of the video, which went viral and was replayed repeatedly on US news broadcasts.

The incident comes at a time of heightened racial tensions in the wake of a series of high-profile incidents involving questionable use of sometimes lethal police force in black communities across the United States.

- Long list of violations -

The US Justice Department has launched investigations into possible civil rights violations by police in a number of the cases.

Long-simmering tensions erupted into weeks of sometimes violent protests after the fatal shooting of unarmed black teenager Michael Brown in Ferguson, Missouri, in August.

A grand jury declined to indict the officer who shot Brown and investigators with the US Justice Department later concurred that he acted in self-defense.

The family of 12-year-old Tamir Rice, who was shot dead by police while holding a toy gun in Cleveland in November, is still waiting to hear if prosecutors will charge the officers involved.

The sheriff's department was called in to investigate and reportedly handed its conclusions over to prosecutors last week.

Community leaders tried to bypass prosecutors Tuesday by filing an affidavit with the county court asking for a judge to issue arrest warrants for the officers.

A number of other incidents that gained national attention in recent months have led to criminal charges against the officers involved.

A white police officer who was videotaped shooting an unarmed, fleeing black motorist in South Carolina was indicted on murder charges Monday.

Michael Slager, who served with the North Charleston police force, was indicted for murder in the killing of 50-year-old Walter Scott on April 4.

Slager was dismissed from the force and arrested a short time after the release of a bystander's cellphone video that shows Scott running away as Slager pulls his gun and fires eight shots, five of which hit Scott in the back.

Six officers face criminal charges in the death of Freddie Gray, 25, who succumbed to a serious spinal injury suffered while in the back of a police van in Baltimore, Maryland.

Gray's April death sparked days of sometimes violent protests in Baltimore -- which is just an hour's drive north of the US capital -- and in other major US cities.
