FFF,
The problem with answering that question is that Chief Officers (ACPO) cannot progress through the 3 stages in one force. i.e. ACC,DCC and CC.
An ACC for example can do DCC in their force, but must then move to another force in order to get promoted to CC. Some, - called the "butterflies", move several times. So its not a simple question to answer. The problem with Kent, was that for years they had a long term CC who was diametrically averse to air support. Many of his staff learned their trade under that regime. That attitude stuck for years.
It has changed in more recent times, but the force has no in depth experience of operating aircraft. At one time they were keen on drones.
News tonight! At least one Chief Constable has got the B***s to stick to his guns and has resigned over the question of Police Commissioners. He was also known to be very concerned re the cuts to Police budgets! Well done him!
