Philadelphia's top cop says a rush to provide the public details on a police-involved shooting led to a since debunked story that the victim was reaching into a car for a gun when he was killed.

Commissioner Charles Ramsey says Thursday that police were caught between the media's demand for information quickly on last December's shooting of Brandon Tate-Brown and the need for a thorough investigation first.

Surveillance videos and interview transcripts released Tuesday show Tate-Brown running around the back of the car toward the passenger side when he was shot. His family now accuses the police of lying about what happened.

But the officer told investigators he feared Tate-Brown was running to grab a gun in the car after struggling with police. The officer has been cleared of criminal wrongdoing.
