Ten people have been arrested at a raucous protest at a Philadelphia community meeting after the district attorney declined to press charges in a fatal police-involved shooting.

District Attorney Seth Williams said Thursday that the death of 26-year-old motorist Brandon Tate-Brown in December was a tragedy but not a crime.

Williams said surveillance video and other evidence corroborated the officers' story that Tate-Brown was reaching back into his car for a loaded pistol when an officer opened fire.

Protesters unhappy with the decision shoved police and threw chairs at a recreation center in the city's Lawncrest section.

They demanded Williams and Police Commissioner Charles Ramsey release the names of the officers in the shooting. Ramsey declined, citing their safety. He called the crowd's display embarrassing.

No one was seriously injured.
