I'm sorry, there's no polite way of saying....... "Bollox". That's the kind of number plucked from thin air on the basis of "if you are going to tell a fib, make it a good one."
Actually, the 2008/9 cost to the UK economy of an "Un-natural" death was 1.2M, - (Home Office/NHS figures). I believe, but cannot confirm that the 2009/10 figure is closer to 1.4M.
The "ACPO" cost for Air Support, (2010/11) is 63.5M which they hope and pray will fall to 42M under the National project. (Source: NPIA briefing document dated 12.11.10).
