About two dozen community activists criticized the Los Angeles Police Department and Chief William J. Bratton on Tuesday for breaking a promise to keep the public informed about the investigation into the fatal shooting of 13-year-old Devin Brown. "We are concerned the process is under a cloak of secrecy," said the Rev. Lewis Logan of Bethel African Methodist Episcopal Church at the Police Commission meeting in downtown Los Angeles. The church is a short distance from the spot in South Los Angeles where Officer Steve Garcia fired his handgun 10 times, killing Devin on Feb. 6. "We want accountability on a weekly basis," Logan said. Nation of Islam minister Tony Muhammad, one of more than 100 protesters, said: "The Police Department is saying it is transparent. It is not transparent. That's a lie. You cannot tell us nothing."
