I suspect there is a bit of historical baggage here. In the 1970s the Met used Enstroms as an early experiment in police aviation. My aircraft was one of those, and after its second power failure, the powers that be, decided twins were the way to go, and that is the way it has stayed.
Neither emergency landing damaged aircraft or property, but did the reputation of singles over the city no good at all. The relevent problems have long since been solved but the antipathy to singles remains 30 years on.
