I'd like to play devil's advocate for a bit: are we ignoring the value of credibility with cops? Cut off benefits previously promised, and you find potential workers no longer trust you. This really is devil's advocate, because I think pensions are outdated and shouldn't be offered to new workers. But part of the bargain with the civil service has been, basically, lifetime employment + retirement. There are costs to backing out on that.
