Pistol whipping off duty Cop doesn't work out

This dashcam footage shows an off-duty police officer in Milwaukee, Wisconsin. On his way to work, he gets in a minor fender-bender with another driver, who decides the appropriate decision is to brandish a firearm and strike the officer with it. The officer, a 21-year-veteran, is not intimidated and draws his own firearm. In the ensuing gunfire, the suspect is hit and killed, while the officer is unscathed apart from the head injury. Viewer discretion is advised. The suspect, at this time unidentified apart from his 23 years of age, hits the officer in the mouth with his pistol at the approximate 40 second mark. Relatively calmly, he draws his own pistol and manages to fire on the suspect, despite the suspect already having his weapon out. The suspect clearly thought he held all the cards here, but you can almost see his OODA loop grinding to a halt as he realizes he's picked the wrong guy to try to bully. He tries to use his car for cover but the officer keeps lighting him up when he tries to emerge. Then the penny drops: "Milwaukee Police." Uninjured by the suspect's ineffective gunfire, the police officer shown was placed on administrative leave after being treated for his facial injury, pending an investigation of the shooting- normal practice for an OIS. No other persons were harmed.
