We have a number of sites in the UK for reporting crime which are supposed to be anonymous. The best known is Crimestoppers UK [1] which tells you you can "Contact us anonymously with information about crime". All these sites use Google Analytics and some also add Facebook tracking codes too.

None of these sites point out that Google, Facebook, etc can easily ID you and while you may be anonymous to the site operator you aren't truly anonymous. I've contacted Crimestoppers and the local police to ask about this and got nowhere. The bottom line seems to be that the police and Crimestoppers have absolute unshakable faith in Google and are comfortable outsourcing crime victims' privacy to an American advertising company.
