Friendly Fire?  You guys hear about this?

SEATTLE — Police officers in two patrol cars fired more than 20 rounds at each other in a frightening gun battle before realizing they had mistaken each other's vehicles for a stolen police car.

Nobody was hurt, but one of the cars was apparently riddled with bullet holes.

The whole incident started when an officer spotted a young man behind the wheel of a patrol car early Tuesday morning and gave chase. While in hot pursuit across Seattle, the officers involved in the high-speed chase lost sight of the patrol car.

During the confusion, officers in one car saw that another police cruiser appeared to be maneuvering or trying to block their way and the two cars collided. Some officers drew their weapons and fired, assuming the other patrol car was the suspect's vehicle.

Meanwhile, the young man in the stolen patrol car returned the vehicle to the precinct where it belonged, police said. As he tried to walk away, officers noticed him and placed him under arrest.

As it turns out, the suspect is the son of a former Seattle police officer who died in 1995 when a suspect leading police on a chase crashed into his car. Zachary Davis, 18, faces charges of stealing a police car, eluding arrest and impersonating a police officer.

A police spokesperson told ABCNEWS affiliate KOMO that Davis had been "adopted" by the department since his father's death. Davis worked at times in the communications center and regularly went on ride-alongs with officers.

Police won't say much about why Davis may have stolen the car, but say he has emotional problems. He was found wearing a police officer's uniform shirt, body armor and a collapsible nightstick. He was not carrying a gun.

"Mr. Davis obviously is suffering from severe emotional problems," Chief Gil Kerlikowske told The Seattle Post-Intelligencer. "Many officers who have known him since he was born are very concerned about him."

Only one of the cars was riddled with bullet holes?  Where did the other bullets go?  

Shouldn't the police get a good look at the person they are trying to shoot at?   Sheesh.

PS.  Lousy shots.
