The federal government has been accused of collecting data on all forms of communication, including the complete contents of private emails, cell phone calls, and Google searches, as well as all sorts of other personal data, so they will have the knowledge to concoct all kinds of charges if they want to target anyone.
They feel that they have the authority to do this in Section 215 of the Patriot Act, which gives them license to take all commercially held data about us.
What happened to the Fourth Amendment of our Constitution, which protects us against unreasonable searches and seizures? This amendment was also violated in the Boston Marathon bombing incident when they searched private homes without a warrant.
Welcome to 1984, where Big Brother wants to watch every move that we make. We must also remember that trading away civil liberties for security results in the loss of both freedom and security.
