Police released two videos showing an officer fatally shooting an unarmed black man in a San Diego suburb and said they hoped showing the footage would ease escalating tensions.

The videos show the officer fired four times at close range almost immediately after Alfred Olango, 38, suddenly raised both hands to chest level and took what was described as a shooting stance.
