As traffic police warden/observer, maybe.
As proper 'action' police chopper, you must be joking (putting twin requirement aside for UK)
That isn't to say that you don't have some R44 a la Police in the US or some budget force countries further South/East.
Could they at least put fenestron tail rotor on that 'special' version of R44 so that it looks somewhat better and quieter for such police op?
