Recently RUSI, a Whitehall "think tank" published a report 'Big Data and Policing: An Assessment of Law Enforcement Requirements, Expectations and Priorities', with 54 pgs. and there is a comprehensive summary on this link:https://rusi.org/publication/occasio...t-requirements

It is very UK-centric report, so little mention is made of the various US experiments and schemes.

Today's The Independent on Sunday has an article, based on the report, but has some other comments:http://www.independent.co.uk/news/uk...-a7963706.html
