A small group in Arizona is protesting a decision not to charge a police officer in the shooting death of a woman accused of shoplifting and threatening the lawman with scissors.

The March shooting of 27-year-old Navajo woman Loreal Tsingine (SIN'-uh-jin-ee) led tribal officials to urge the U.S. Justice Department to investigate the treatment of American Indians who live in towns bordering the reservation.

About 20 people chanted Monday outside a prosecutor's office in Phoenix days after its independent review found no evidence of criminal conduct by Officer Austin Shipley of the small eastern town of Winslow.

Shipley fired five shots at Tsingine after responding to a shoplifting call at a convenience store.

Records show that two officers who trained Shipley had serious concerns about his work and one recommended the police department not keep him on the force.
