The city of Milford, Conn., may join the growing list of municipalities in the state that are administering Breathalyzer tests at school functions to enforce bans on alcohol possession or use. If the school board adopts a new policy being promoted by Superintendent Harvey Polansky, students could be subjected to breath testing if adults suspect they have imbibed. Alcoholic beverages are barred from school grounds and events, but that doesn't stop some students from showing up inebriated.
