Anyone who actually takes up the idea of returning to the UK right now must be off their rocker... no matter what your work is. We're going to the dogs, and fast. A few extra plod won't solve anything.
It made me laugh the other day when Gordon was spouting about some government initiative creating 3000 new jobs... with various sources claiming UK unemployment figures are approaching 2 million, I don't think it will really help; neither will attempting to persuade 130 coppers to return to Leicestershire.
