FWF,
From the viewpoint of the commercial operator, I think you have hit upon one of the possible ways in which this "consultation" could go, if we aren't aware of the issue.
In general, Joe Public who complains about noise does not differentiate between the uses of helicopters - they don't really care. The police heles are going to operate within the CAA POAM rules but essentially as they see fit. They will operate at night, when perceptions of noise are greatest, which will annoy some people. If it is night time and a noisy hele, it pretty much has to be the police.
It would be quite easy for hele-haters to have a go at the commercial operations (because they can), when the source of their antagonism will be immune from any additional restrictions that Red Ken may be able to get imposed.
This isn't a pop at police ops - it is just suggesting that those representing heles need to force the nature of different ops to be appreciated.
