Old bill in doing their job shocker

what about being helpful, and trying to ensure that the policemans job gets done in as efficient manner (and therefore cheaper, for us, the taxpayers) as possible.

This, like the idea that you are meant to help the police (or meant to do anything), needs a context to make any sense - you would need to add in who means you to help the police, why you should be helpful and so on, without this context it appears to be simple unthinking obedience.

I can't take your defense of the open dissemination of personal information as a cost cutting measure seriously.

My job involves going to different departments, receiving and giving out information. its really hard to do it when people are being unhelpful 'just because they can'.

Straw man.

Maybe no one ever helped you out?

Ad hominem.
