I often read Charles Stross's blog (good SF writer, http://www.antipope.org/charlie/blog-static/index.html) and he comments about the big brother tactics of the British police. In addition the British don't have the same guarantees of privacy and freedom of speech that we do in the US. You can be successfully sued for libel even if what you say is true. A British citizen can be sued for a posting even if the server is in another country. Scary.
Anyone can be sued for libel in Britain for any content that is read by even one person in Britain.
Rachel Ehrenfeld was successfully sued in Britain by Khalid bin Mahfouz for writing Funding Evil: How Terrorism is Financed and How to Stop It, a book that was never published in Britain. 23 copies had been shipped to Britain by online booksellers, which was enough for Britain to claim jurisdiction.
British libel law also makes web hosts, printers, bookshops etc. liable, so it is very easy to get anything out of circulation by going after the weak link in the chain: that is how Alisher Usmanov go Craig Murray's blog taken down withot actually Murray himself.
