Some useful numbers and links on CCDP and its predecessor Govt IMP
£12Bn
Only listed number for price of the IMP, which was for a centralised DB.
I think merging the outputs from the various ISP hosted systems will bump that up a bit. But that part is secret, not the £2bn the govt say they will give ISPs to do their work.

So the UK govt plans to spend £1m *each* to watch these suspects (Note that's just the stuff for the ISP'. There is *no* stated figure for the GCHQ end of the bill). or they will spend £33.8m each to save 1 life.
Or it plans to watch *every* person in the UK because 0.0032% *may* actually do something that will endanger other peoples lives, possibly. It will spend at *least* £2Bn to do so.
