The Governments Snooping Laws

So it looks like the Government will finally get the law passed requiring websites to retain all user browsing activity logs for a minimum of 1 year.
I really cannot understand how this will achieve much at all.  The real criminals arent going to do much "in the clear" and the odd time something does lead to conviction will be so minimal that it wont be worth all the effort.
Its a shame the logs arent protected under the data protection act by the ISP, as it would make life a little more difficult.
I guess if this concerns you, now is the time to go TOR if you arent already.
