New Fairfield Resident Troopers and town Police are stepping up patrols in shopping centers around town.  Business owners have requested that they be more visible due to a rash of daytime larcenies, including catalytic converters thefts.  The Trooper's Office says they have received some criticism for patrolling the shopping areas and taking action on fire lane violations, but State Police say  standing, stationary or parked vehicles- occupied or not do make for a violation of state law.  They encouraged those taking issue with the enforcement of fire lane parking laws to see the Fire Marshal.
