If you’re under 21 and try to buy alcohol in New Jersey, you could be busted by an undercover cop. On Thursday the Division of Alcoholic Beverage Control kicked off their “Cops in Shops” underage drinking enforcement campaign. Local police officers will be stationed at area liquor stores as employees to monitor possible liquor purchases by minors. Since the annual program began in 1996, the Attorney General’s Office reports that over 10,000 arrests have been made. Participating towns will receive grant money to assist with implementation of the effort. Locally, grant recipients include Avalon, Lower Township, North Wildwood, Wildwood and Sea Isle City.
