"The Evening Standard also understands that
US secret services have a number of secret files on Diana and her closest associates that are held by the national security agency. The files, which include reports from foreign intelligence - thought to include MI5 and MI6 - come under both top secret and secret categories.The reports cannot be released because of "exceptionally grave damage to the national security". The documents on the princess seem to have arisen because of the company she kept rather than through any attempt to target her."
http://www.thisislondon.co.uk/news/article-23377815-details/Diana+was+bugged+by+secret+service+in+US/article.doIt never ceases to amaze me how ignorant people are of other countries, even journalists. If the stupid fuckers had just read the original story, then they would have seen the bottom paragraph, which clears up the usage of "secret service".
Secret Service is a proper noun, and refers to the American security agency tasked with protecting American dignitaries and the production of money.
The common noun "secret service" is equivalent to the word "intelligence agency" in general. In fact the story writer actually uses "US intelligence agencies" in the story, which should have shot down any confusion! But oh no, stupid Americans, we can't figure simple fucking language out!
