(CNN)To allay possible concerns, Boston prosecutors released video Friday of the shooting of a police officer last month that resulted in the killing of the gunman. 

The officer wounded, John Moynihan, is white. Angelo West, the gunman shot to death by officers, was black. 

After the shooting, community leaders in the predominantly African-American neighborhood of Roxbury, where the shooting occurred, were quick to call for calm. One said the officers were forced to return fire. 

Still, they were glad to see the video released for the sake of transparency. 

"I think people understand that the decisions Mr. West made put his life in grave jeopardy," clergyman Mark V. Scott told CNN affiliate WCVB. 

West had several prior gun convictions, police said. 

Moynihan is a former U.S. Army Ranger who was honored at the White House for his heroism in the wake of the Boston Marathon bombing. The "Top Cop" helped save a transit officer wounded in a gunbattle with the bombers. 

Last month, he became a gunshot victim when he and other officers in unmarked cars, but with blue lights flashing, stopped the car West was driving. 

When Moynihan opened the driver's-side door, the video shows, West sprang out and fired a shot with a pistol at the officer's face. As West ran away, he fired back at the other officers with his .357 Magnum handgun, police said. They returned fire and killed him. 

Moynihan, 34, survived with a bullet wound under one eye. He was placed in a medically induced coma at a Boston hospital.
