Terrorists would be dumb to communicate using plain email anyway. There are many more ways to communicate anonymously and securely.
If I was a terrorist I'd just embed encrypted text inside an image and post it to an image hosting site or image based usenet forum, or use one of the encrypted peer to peer networks. Throw in a proxy or two and nobody knows who you are communicating with and what you are saying. It ain't rocket science.
I can see a business opportunity for someone here, if the business does not already exist: Provide an encrypted email forwarding service. So you can create and send an encrypted email with the real destination address encrypted within the message, then the business in the middle decrypts the destination email address and forwards it on. The body of the email or any attachments would be encrypted with a different key so only the sender and final recipient could decode the email. Simple. Completely bypasses the UK Governments security measures. The only downside would be that subscribing to such a service could look suspicious anyway, even if the Govt could not snoop on what you were communicating or with whom.
Well The Pirate Bay already launched a VPN service for BitTorrent so copyright organisations can't trace pirates... I guess this will come soon.
