Its been 4 years since you posted this. Assuming you're still interested in finding the answer, im an Lt. in the NYPD patrol bureau and here's your answer. NYPD does not and will never have ice cream trucks! Complete waste of useful money. Mr. Softee is the biggest seller of ice cream trucks in NYC. The colours come in blue and white by default, making you think it's NYPD. In the picture it looks like an NYPD cruiser and 2 ESU trucks are parked next to the ice cream truck or the ice cream truck is parked at the police station. I can see why you think its an NYPD ice cream truck because of the colors but it's not Hope I helped, Lt. Anon, Patrol Bureau NYPD.
