"On the other side of the argument, Catherine Crump, acting director of Samuelson Law for the Berkeley School of Law, focused her argument on the dangers of providing a backdoor to any device to the government and expect it to only be used by the “good guys.”
She drew a parallel between handing the FBI a second master key to iPhones and recent worldwide WannaCry ransomware attack, which was launched using leaked National Security Agency (NSA) exploits.
“The problem with that is you cannot build a backdoor that works only for the U.S. government, good guys or other people with good motives," Crump argued. "If you build it for them, encryption will be weakened for everyone.""
