Re: £4m doesn't go far

For goodness sake, it's an underfunded project to achieve an unclear goal using uncertain technology.
Previous attempts at this sort of thing have proved unsuccessful at best, and a public relations disaster at worst, and there is nothing in this project to suggest it will fare any better. How far do you think £4m split 13 ways goes.
And I'm not sure it is even desirable - it is always a bad idea in the long run to build tools which can be trivially repurposed to suppress dissent - how do you think China, Saudi Arabia and your local police force will repurpose and abuse this if it worked?
