Chicago police 'possibly violated' policy in shooting

Chicago's police superintendent has said videos of the police shooting of a black man in the city last month indicate three officers may have violated the department's policies.

Eddie Johnson said on Saturday that it was against departmental policy to fire at or into a moving car when the vehicle was the only potential use of force by a suspect, and police were taking a hard look at training and tactics following the shooting.

Johnson said the lack of a body-camera video of the shooting of 18-year-old Paul O'Neal is under investigation, though he noted that the officers in that police district had the cameras for only about a week before the shooting.

Reverend Jesse Jackson, the US civil rights activist, said the lack of a complete video accounting of O'Neal's shooting showed a cover-up.
