School may have been out this past summer but scores of people attempting to flout New Jersey’s drinking laws learned a tough lesson thanks to the state’s Cops in Shops program targeting underage drinking. The summer enforcement initiative resulted in 252 arrests. A record 39 shore towns from Atlantic Highlands to Wildwood this year participated in the program that employs undercover cops to crack down on underage drinkers and those who buy alcohol for them. This past summer $81,000 in grants were received by towns who used the money to pay local police to work undercover in participating retail locations. Law enforcement officers either posed as store employees or were positioned outside the establishment to apprehend lawbreakers attempting to purchase alcohol for underage drinkers.
