Dennis Montgomery is the designer of the computer system known as HAMR (Hammer}. The system was designed to be used against foreign terrorists in the United States, however during the Obama administration it was used against ordinary American citizens and political opponents of President Barack Obama.
On June 5, 2017 James Comey was sued by Dennis Montgomery, alleging that Comey and other government officials covered up evidence showing widespread illegal spying on 20 million Americans. Montgomery presented evidence that “[t]his domestic surveillance was all being done on computers supplied by the FBI...these supercomputers, which are FBI computers, the CIA is using them to do domestic surveillance." More than 20 million American identities were illegally unmasked - credit reports, emails, phone conversations and Internet traffic, were some of the items the NSA and CIA collected. The suit divulged evidence that the FBI has a ”pattern and practice of conducting illegal, unconstitutional surveillance against millions of Americans, including prominent Americans such as the Chief Justice of the U.S. Supreme Court, other justices, 156 judges, prominent businessmen, and others such as Donald J. Trump." The suit also named other defendants as well, including current NSA Dir. Mike Rogers, former CIA Dir. John Brennan and Barack Obama.
