Elected Police Commissioners

In the UK we are to have Elected Police Commissioners who will have powers to hire and fire Chief Constables! Candidates can (presumably will?) seek election on party political platforms! Knowledgeable experienced police officers are to be controlled by ignorant and ill informed politicians. As if the dead hand of political parties had not spread far enough we are now going to hand control of yet another key service to these unrepresentative minorities. Who is supposed to benefit from this nonsense?
