Going S/B on Second from Techny going toward the north lot of Glenbrook N High School, officers sit on resident’s driveways getting kids going over the 20 mph speed limit all the time, mostly in the early morning and afternoon hours when the student are coming to school or leaving..They also are on foot with a handheld radar gun and have a squad car standing by to catch speeders when info is relayed using their radios..It is a residential street
