Apparently someone else thinks they're professional enough

The Glendale police detective was driving his personal vehicle Monday afternoon when a car pulled up behind him and started flashing red and blue lights, said John Balian, a Glendale Police Department. The detective pulled over, thinking it was an undercover officer. When the man got out of the car, he identified himself as a police officer, flashed a gold badge and told the detective to slow down.

After the detective asked to see a picture ID, the man became nervous and fled in his car. The detective wrote down the car's license plate number and police traced it to 22-year-old Shabod Hosseini of Glendale, Balian said. Hosseini was arrested Tuesday on suspicion of false imprisonment and impersonating a police officer.

Ooops.
