A 37-year-old married cop in New Jersey, USA has been caught pulling over male drivers in traffic stops - and showing them his penis.

According to the Smoking Gun, Jason Miller's is currently being charged with official misconduct and public lewdness.

Apparently the evidence against him is quite damning - his own police cruiser caught video footage of his unorthodox approach to law enforcement.

At least five men got a view of his genitals, one being repeatedly asked if he noticed if the officer's fly was down.

This isn't the only thing he is in trouble for, in one of the cases he stopped a man who said he was coming from a bar and had a few drinks.

He didn't so much as write up a ticket, but according to the affidavit “you can hear what appears to be the sound of a zipper opening and/or closing.”

Miller is not the only cop who has gotten into trouble for his penis appearing on video this year.

NYPD Lt. Alexander Rojas is getting sued by precinct cops Maria Lampley and Claudia Melara, both 35, and Dawn Sprague, 43, for repeatedly flashing his penis at them.

The New York Post reports that he also repeatedly showed the women footage of himself "engaged in masturbation and other sexual acts” despite them repeatedly telling him to stop it.

Another officer, this time in Miami, is facing disciplinary action after he was caught on video masturbating in a high school.

43-year-old officer Steven Rodgers apparently allowed someone to film him as he masturbated inside Edison High according to Filming Cops.

“The school district, along with the police department, uh, we do not condone this type of behaviour,” Miami-Dade Schools Police Chief Ian Moffett told reporters.
