WARNING!! THIS IS FIRMLY TONGUE IN CHEEK!!!
So I guess - based on seeing them in action on the ground - that a police force seeking to employ PCSO's as air support observers is obliged to fit additional seats in the aircraft.
To date I have rarely seen 'silver tops' wandering around in groups of less than two - usually 3 - at a time.
I suppose if they are very small there may be room in the [excess] baggage compartment.
