Lawsuit: Supervisor negligence led to police shooting A lawsuit filed by a police officer in Tennessee says negligence by his superiors led to a police shooting in which he was wounded by friendly fire

NASHVILLE, Tenn. -- A lawsuit filed by a former police officer in Tennessee says negligence by his superiors led to a police shooting in which he was wounded by friendly fire and a black man was killed.

News outlets report former Nashville police Officer Samuel Galluzzi filed a lawsuit Friday saying he was left permanently injured because his supervisors didn't follow safety rules.

Galluzzi was shot twice in the leg during the October 2018 confrontation with 31-year-old Sershawn Martez Dillon, who authorities said matched the description of an assault suspect. WSMV-TV says the state Bureau of Investigation determined Dillion only fired his weapon once.

Police Chief Steve Anderson has said that an internal investigation found that the supervisors — Sgt. Harold Wells, Lt. Viviyonne Lee and Sgt. James Boone — didn't follow policy.
