A 26-year-old Navy man is accused of brandishing a handgun during a July 18 child exchange in front of the Oak Harbor Police Department after the alleged victim pulled a knife, according to court documents.

The police officer’s report indicates that a video from the police security camera showed that Justin L. Cooper and his lead petty officer from the Navy base, who was present because of a military protection order, were not honest with police about what occurred during the exchange.

Prosecutors charged Cooper in Island County Superior Court July 22 with assault in the second degree and carrying a concealed pistol without a license.

Cooper’s ex-wife told police that he approached her car during the child exchange and spit through the window into the face of her boyfriend, who got out of the car armed with a pocket knife, the report states.

Cooper went to his car and retrieved a Glock .45 and continued exchanging words with the other man, the report states. Cooper told the police that he was defending himself since the other man was holding the knife like he was going to stab him.

Cooper said he then drove away.

The lead petty officer told the investigators that Cooper stayed on the opposite side of the car from the other man, displayed the gun “in a self-defense manner” and never pointed it at anyone, the report states.

The alleged victim, however, told police that he got back into the vehicle and Cooper again went up to his window, this time allegedly pointing the gun at him and threatening to shoot him, the police officer wrote.

The surveillance video from the police department showed that Cooper had followed the other man back to the car “and then put a gun through the window and pointed it at” the other man, the officer wrote.

A child was inside the car at the time, the report indicates.

The officer also wrote that Cooper had concealed the gun in his pocket during the incident.
