"Suspect!" McDonald yelled, warning his partner.
Both officers leveled their .40 caliber Glocks at the man. Just as he put pressure on the trigger, Pruitt realized that McDonald, directly in front of him, was in harm's way. Not wanting to hit or deafen his partner, Pruitt eased his finger off the trigger.
There were no obstacles for McDonald. He squeezed off a volley of four to five shots that sent the suspect scampering back up the stairs.
With Pruitt shadowing him, McDonald continued to move on the suspect, taking cover behind a pillar that flanked the base of the stairwell. There was no telltale tug at the rear of his uniform belt, no hint that Pruitt felt uncomfortable with their progress.
As the gunman scampered back up the stairs, McDonald realized he still had a shot at the man, a man who had already killed, and was threatening to kill again. But he considered the totality of circumstances. Shooting the man in the back would probably be justified in a court of law, but the court of public opinion was another thing altogether. McDonald resented the reality, and his ability to even contemplate it at this crucial moment. The gunman cleared the top of the stairs and disappeared.
