Radio Controlled Helicopter – for police work?

Just a thought; a real size helicopter is sometimes very useful in police work. An infrared camera can identify people. A night vision camera can “light up” an area at night.
The problem is a helicopter is very expensive to operate and extremely noisy.
The radio control helicopters also quiet enough to not be heard more than 50 feet away and can fly down streets and alleys at as little as one foot altitude and as much as 400 foot altitude.
They can take from 10 minutes to almost instant on to be ready to fly.
Here are two very different versions of a radio controlled helicopter:
