Here is another story (from the well respected Guardian Newspaper) on how our government doesn't follow the 4th amendment when it comes to reading your email. No need for probable cause in order to search...

 

How the US government secretly reads your email

Somewhere, a US government official is reading through a list of those who sent or received an email from Jacob Appelbaum, a 28-year-old computer science researcher at the University of Washington who volunteered for WikiLeaks. Among those listed will be my name, a journalist who interviewed Appelbaum for a book about the digital revolution. Appelbaum is a spokesman for Tor, a free internet anonymising software that helps people defend themselves against internet surveillance. He's spent five years teaching activists around the world how to install and use the service to avoid being monitored by repressive governments. Now, Appelbaum finds himself a target of his own government as a result of his friendship with Julian Assange and the fact WikiLeaks used the Tor software. Appelbaum has not been charged with any wrongdoing; nor has the government shown probable cause that he is guilty of any criminal offence. That matters not a jot, because, as the law stands, government officials don't need a search warrant to access our digital data. Searching someone's home requires a warrant that can only be obtained by proving probable cause, but digital searches require no such burden of proof. Most people are not aware of the ease with which governments – free, open and so-called democratic – can access and peruse our private communications.  Note: For key reports on government threats to privacy from major media sources, click here.
