The Guardian has acquired top-secret documents about the NSA datamining tool, called Boundless Informant, that details and even maps by country the voluminous amount of information it collects from computer and telephone networks.

They can do that, as we know In the United States in 2001, provided for the USA Patriot Act exemption laws  (Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act).
This exemption laws entitle the state in this action in the name of national security.
The Patriot Act laws are very similar to those of what were the exemption laws in Nazi Germany.

The National Security Agency has developed a powerful tool for recording and analysing where its intelligence comes from, but according to The Guardian there will be raising questions about its repeated assurances to Congress that it cannot keep track of all the surveillance it performs on American communications.

We always, since 2001, be aware of this state of affairs on American servers, and therefore we have used by a mobile phone Text Message with impor matters, such as passwords.

A snapshot of the Boundless Informant data, contained in a top secret NSA global heat map seen by the Guardian, shows that in March 2013 the agency collected 97 bn pieces of intelligence from computer networks worldwide.
Also, disinformation entering, into this cyber-spy is possible.
