Law enforcement backdoor? What could go wrong?!

Police would like to have a national backdoor to your private data .... you know, to help them with legitimate police work:

But cybercrime investigators are frustrated by the speed of traditional methods of faxing, mailing, or e-mailing companies these documents. They're pushing for the creation of a national Web interface linking police computers with those of Internet and e-mail providers so requests can be sent and received electronically.

I can think of lots of reasons that this would be a Bad Idea.

I'm sure David could come up with several more.
