Arrested for impersonating officer ... after stopping real officer

Investigators in Florida are describing what we have to imagine is one of those all-time facepalm. They say a 20-year-old man impersonated a police officer by trying to pull over an actual police officer.

This man, Matthew McMahon, was booked and released by the St. Johns County Sheriff's Office Tuesday in St. Augustine by the very men and women they say he tried to pretend to be.

The detective who eventually arrested McMahon told WTLV in Jacksonville he was driving an unmarked car, and he was "shocked" when the Ford Crown Vic behind him flashed a red and blue light bar.

WTLV reporter: "An outdated and out-of-service cop car pulled up next to him."
Det. Chance Anderson, St. Johns County Sheriff's Officer: "So I pulled over to confront the individual, at which point he pulled up next to me, kind of gave me the slow down look and pointed his finger at me."

Bad move, young man. Detective Chance Anderson says he quickly pulled over McMahon.

The booking site for the sheriff's office shows McMahon was arrested on suspicion of impersonating an officer and obstructing police.

The news inspired plenty of embarrassing fake-cop-pulls-over-real-cop headlines.

The detective confirms McMahon has never been a certified law enforcement officer. The ironic thing -- as if this story didn't already have enough?! -- is that Anderson told WTLV part of his job is catching people who impersonate police.
