The reason for this is that no politician is going to willingly step up for more police oversight and restricted powers, for at least a couple of reasons:
1) They will be painted by their opponents as "weak on crime" or even "supporting criminals" at election time.
2) They risk losing votes from emergency services workers, which are quite a large demographic in local elections.
