The officer said he was unable to issue verbal commands before firing, “due to the quickness of the event and the immediate threat Bradford posed” to the two men he was approaching.

The police later arrested another man — Erron Martez Dequan Brown, 20 — and charged him with attempted murder in connection with the shooting of Mr. Wilson, the injured man by the railing.

The attorney general’s report said there was no evidence that Mr. Bradford’s handgun was fired at the mall.

The report said the F.B.I. had found no evidence to prompt an investigation into whether Mr. Bradford’s civil rights had been violated, a basis for federal prosecutions in cases that are otherwise under state jurisdiction. An F.B.I. spokeswoman declined to comment on the matter Tuesday.

The decision not to bring charges did little to quell the suspicions and anger of Mr. Bradford’s relatives and supporters. “I’m outraged,” his mother, April Pipkins, said in a telephone interview Tuesday. “In no way was justice served.”

Some surveillance video images of the events at the mall were released on Tuesday. But Benjamin L. Crump, a lawyer for the family, said he believed there was additional footage that had not been released, and he demanded that the public be allowed to see it. In a prepared statement, he said that Mr. Bradford’s “only ‘crime’ was being black.”

Ashlyn McMillan, a witness to the mall shootings, told The New York Times that she considered Mr. Bradford a hero, saying that he had directed frantic shoppers to safety and had warned her to get down and seek cover inside a store.
