Corey Flagg

Corey Flagg is a former Chicago Police officer headed to prison in about two weeks to serve a 9½-year sentence for robbing drug dealers.
But on Jan. 11 he was playing cop again.
Chicago Police think he made an anonymous 911 call tipping officers that a car parked near 107th and Wentworth contained drugs.
"That is the car," Flagg yelled to officers from a white Ford Thunderbird before driving off, according to a police report.
The officers searched the car, but didn't find any drugs or make any arrests. They recognized Flagg and reported him to their superiors, who notified the feds.
Federal authorities don't suspect he was doing anything nefarious, like trying to set up a rival. They just think he was trying to help the police.
