TF keeps calling them "police" so they keep answering their inquiries. We're talking here about "The City of London Corporation, officially and legally the Mayor and Commonalty and Citizens of the City of London, is the municipal governing body of the City of London" (source: Wikipedia). Part of this is PIPCU, which is funded with taxpayer money.
"Since at least 2011 the BPI (= the british branch/version of RIAA, C.) had built close ties with the City of London Police's National Fraud Intelligence Bureau as well as advertising agencies to remove payment channels from pirate sites. The dedicated unit itself was first announced in December 2012 by Vince Cable MP. It was funded by £2.5m over two years of public money via the Intellectual Property Office and became operational in September 2013. In April 2014 Mike Weatherley, the Prime Minister's Intellectual Property Advisor called on the Prime Minister to commit to the permanent funding of the unit to extend its existence beyond 2015. In October 2014 additional funding was revived to operate until 2017."
Don't be as dependent on scraps like TF and stop referring to them as "City of London Police" which might to the ininitiated be the metropolitan police of the British capital, while in fact it's some corporate task force that abuses the old City situation to give themselves public powers. Think of them like a Omni Consumer Products enforcement group, by Big Business, for Big Business, and paid for by the taxpayer. Can it get any better?
