Then there's this (from August):
"on Friday two New York City police officers engaged in a wild shootout with disgruntled gunman Jeffrey Johnson minutes after Johnson fatally shot a former co-worker.
dramatic surveillance video released by police Friday night showed the confrontation lasted only a few seconds. Johnson was walking rapidly down the street trailed by two police officers when he stopped, wheeled around and pulled out a gun.
About a dozen people ran for their lives, including two small children who were just feet away from Johnson. He pointed the gun at the officers, who quickly fired at him.
Johnson dropped his briefcase, fell to his knees and then collapsed on the ground.
The bystanders likely were hit by police officers' stray gunfire, some of it bullets that rebounded off planters in front of the skyscraper and grazed pedestrians. The two officers fired 16 shots. The surveillance video shows Johnson pointing his weapon at police, but it's likely he did not get a chance to fire, investigators said."
