Officer Drew Fiorello, liaison officer between Walt Whitman High School and the Second Precinct of the Suffolk County Police Department, will address parents and community members at 8 p.m. Tuesday in the Walt Whitman High School library. Fiorello will give a short presentation on some issues that affect older teens: the new Suffolk County social hosting law ( a ban on serving alcohol to teens in the home); teen driving (permit and license requirements); what parents should do if a teen gets involved in the court system, and parental responsibility. This will be followed by a short question and answer session. All are welcome to attend.
