"Fresno Police Chief Jerry Dyer announced Tuesday that his department will continue undercover bar stings targeting drunken drivers, but some changes were made to the program. The next operation is scheduled for Friday, which is St. Patrick's Day. Police have not yet determined which establishments will be monitored. Dyer said undercover officers will not be positioned inside bars or restaurants. They will only be outside the bars and in parking lots. The chief also said officers — preferably uniformed — will approach people who appear to be intoxicated to dissuade them from driving."
