Here is one more reason why we cannot trust the FBI or any other government agency or law enforcement agency with “back doors” to encrypted information: the information obtained and supposedly kept secret by these agencies won’t be secret for very long.
One of many examples is the recent revelation that Russian agents have dramatically improved their ability to decrypt certain types of secure communications and successfully tracked devices used by elite FBI surveillance teams. Officials also feared that the Russians may have devised other ways to monitor U.S. intelligence communications, including hacking into computers not connected to the internet. Senior FBI and CIA officials briefed congressional leaders on these issues as part of a wide-ranging examination on Capitol Hill of U.S. counterintelligence vulnerabilities.
Whatever the FBI and other agencies know will soon be known by the Russians and undoubtedly by other governments and even by private hackers around the world. If the Russians can crack into communications, undoubtedly so can many other evil people.
