President Bush signed the Postal Accountability and Enhancement Act into law December 20th.
Included in his signing statement is the following:
...The executive branch shall construe subsection 404(c) of title 39, as enacted by subsection 1010(e) of the Act, which provides for opening of an item of a class of mail otherwise sealed against inspection, in a manner consistent, to the maximum extent permissible, with the need to conduct searches in exigent circumstances, such as to protect human life and safety against hazardous materials, and the need for physical searches specifically authorized by law for foreign intelligence collection. ...

Apparently, we can construe this to mean the government may now open our mail without a warrant if the mood strikes them.
What's next? A little mini-camera in each room of the house?
