On one hand, it's reassuring to know that Yahoo will work with law enforcement to bust criminals, digging through their private messages to get the job done. On the other, $60 is a low price for our privacy.

For $20, Yahoo will give subpoena-wielding authorities your basic user ID information. For $30-$40, that jumps to the contents of subscriber accounts, including email. And for $60, police basically own the place. Full contents and logs of Yahoo Groups are at their disposal.
Of course, it's good that Yahoo keeps these prices in check, only charging authorities cost for retrieving records (meaning your taxes pay Yahoo less than they could). Then again, it's flat-out alarming to consider the data trail we all leave, its surprising permanence and the ease with which it can be accessed.
And if you really want to be freaked out, Cryptome is assembling these lawful spying policies by company. Their list already includes communication providers Cox, SBC, Sprint and AT&T.
