Policeman at Texas pool party resigns

A Texas police officer videotaped pulling a gun out at a teen pool party resigned on Tuesday in the latest racially charged incident involving the use of force.

McKinney Police Chief Greg Conley denounced Eric Casebolt's "indefensible" behavior, insisting it did not reflect the department's "high standard of action", though the officer was not pressured to quit.

Officer Casebolt, who is white and seen on video shouting obscenities at and forcing a teenage black girl to the ground and at one point pulling his firearm after two males rushed forward in apparent protest, resigned from the police force on Tuesday.
