If the lodge keep saying that 'members are policemen' then by all means find out their shoulder numbers, and report them to Hampshire Police Professional Standards department for a violation of their code of ethics (http://www.college.police.uk/en/20972.htm)
Even with the masons, they can't get past that, and any police officer found to be using his power for the benefit of the lodge, rather than the public, will be SACKED (Hampshire are quite harsh with their rules) even if they are the Chief Constable.
