A good analogy of how the public sector works, using a private sector example, would be the paralysis that beset IBM after the anti-trust case was filed against it in the mid-70s. Everything anyone tried to do in terms of product development, research and sales/marketing had to be approved by a battery of lawyers to ensure that it didn't harm the defence case IBM was mounting.
The equivalent in the PS is that every time you try and do something new instead of a court ruling to worry about, you've got the press, the blogosphere and every other medium of communication where the errors of private industry go mysteriously under-reported, yet the tiniest fuck up, or slightly progressive policy change made by an LA, PCT, Hospital or Whitehall department will be subject to intense and largely public critical scrutiny.
As for accountabillty - I believe the public has a right to see how money is being spent. However, the public seem to believe that those who work in the public sector (for example) should only be working in buildings that are old, with 30 year old computers and telephone systems that don't work. When a public sector body spends money on marketing a message (say for example the DOH and healthy eating) the press will decry it as a waste of money, the nanny state spending our tax ££s etc, while conveniently ignoring the combined spend of McDs, Coke, Pepsi etc annualy is more than 10 times the total government spend across all communications media.
So before you start banging on about transparency and accoutabilty, take into account that the public sector shouldn't be some scrimshaw operation wrt the conditions and equipment it's staff work with, and that for every single report asked for, the information has to be collated, analysed and put into a document and context which minimises the chances of wilfully incorrect interpretation (e.g. fixing on a single line or statistic and making that the whole story). Plus of course that it costs money, and creates exactly the kind of arse covering mentality everyone on here is bitching about.
