The NSA is violating the rights of privacy to all US citizens with the use of mass surveillance on random citizens' internet-accessible devices, showing unlawful and unrightful behavior.
Although not written in the Constitution, the right of privacy is stated in the Bill of Rights. The NSA is breaking into popular websites and hacking computers, tablets, and cell phones to gain information about any citizen who resides in the United States. All Americans have a right to keep which information private they prefer, though the NSA ignores this matter. They link servers of popular websites (Angry Birds, NY Times) to their own servers to gather information. Information can be tracked on your device at any time, being left unknown.
