THIS is the shocking moment a cop smashes a man’s car window before hitting him twice in the head.

Footage appears to capture the aggressive traffic stop by Jacksonville Sheriff’s officers – and has since gone viral on social media.

An alarming event was shared on Instagram by @904will, who mentioned in the caption that he was stopped by the police in February due to an issue with his car’s headlights, even though there was “no rain, smoke, or fog” at the time.

The video captures the driver sitting inside his vehicle, questioning an unseen police officer about the reason for being stopped, supposedly for not having his headlights on.

The driver is heard saying: “There’s no rain.”

A cop responds: “It doesn’t matter – you’re still required to have headlights on.”

The driver then asks to see the law, before the officer says they’ll show it to him once he agrees to step out of the car.

He then asks for “a supervisor” – but, as written in the post’s caption, “things escalated quickly”.

The cop stood behind the driver is then captured on footage shockingly shattering the window with two hits using his fist.

He then swaps hands and gives a final punch to the window, with the driver covered in glass with a shocked, scared expression.

The cop is heard shouting: “Exit the vehicle now.”

He then proceeds to disturbingly hit the driver in the head, repeating for him to exit the vehicle.

The driver is then asked to show his hands, which he does willingly as cops then open his door and rip him out of the car.

He then appears to get punched in the head by the same cop and slammed on the ground.

The apparent victim in the horrific encounter said in the caption of the video that he suffered “a chipped tooth and nine plus stitches in my lips”.

He also said he endured “a concussion and short term memory loss” – adding how “very hard” it was on his mental health.

The caption reads: “I’m not mentally healed from this but I had to get the word out eventually.”

Jacksonville Sheriff T.K. Waters said on Sunday that an internal investigation has been launched.

The statement said in part: “We are aware of a video circulating on social media showing a traffic stop represented to be from February 19, 2025.

“We have launched an internal investigation into it and the circumstances surrounding this incident.

“We hold our officers to the highest standards and are committed to thoroughly determining exactly what occurred”.
