In one scene, there's a New York Police Department car(Car #1097) with a New York State passenger vehicle license plate on the front bumper. New York City police cars only have their own license plates identifying the car number, and only on the back. In fact few police departments in New York State use state plates for their cars, and those that do only use Police license plates.
When Maureen is gunned down after exiting the car, cables can be seen running from her leg to the car, presumably connected to the squibs setting off the blood bags on her torso.
