Chris Hansen may no longer be catching predators on NBC, but the Greenville, SC police department is setting to sting operations to curb underage drinking. Officers posted an ad on Craigslist inviting adult men to a party hosted by a 19-year-old girl. In order to gain entrance to this party, the men must bring alcohol. Once they handed the liquor to the 19-year-old decoy, cops swooped in -- To Catch a Predator-style -- and arrested the men and charged with transferring alcohol to a minor. Twenty men were arrested.
