If you think its bad in the military you should hear my friends in the Police about the battles that go on to try and push work (and especially overtime) onto someone else's budget line while retaining the bodies and tasks in your own hands....
They tend to choose whatever is in the news at the moment - so everyone right now is trying to shove things onto People Trafficking and Illegal immigrants as they think the Home Office will pick up some of the tab. So if you're stopped and asked "Is that woman in the front seat a Romanian refugee, Sir" you can guess which box it'll go under.
