Ah yes, damn that dihydrogen monoxide... On a serious note though, I'm not intending to start an angry argument here, but personally I don't see the problem in my emails being copied to the Government / the Police. I don't send any emails that I'd be embarrased by if a third party read them - and if I was going to be writing such emails, then the knowledge that they would be read would almost certainly deter me from sending them. The zealous protection of music copyright does irritate me, but I am perfectly comfortable with surveillance - it may not stop terrorism, but it could help prevent / prosecute other crimes too.
