Falmouth just received federal grant money to buy a police helicopter, I have routinely seen it on patrol above the town, usually accompanied by a cruiser on the ground stopping the cars the helicopter gets on radar. The new (35 million dollar) station has a pad on the roof for the helo to land on, and one of the officers already had his private helicopter license, so it was an easy transition for the department. Be careful anywhere near the bay/rivers as well, as Falmouth routinely uses their patrol boat they got from the Coast Guard to use LIDAR on cars traveling along the roads/bridges near the waterways. The accompanying cruiser then picks up the speeder after being radioed from the boat/helicopter.
