I am no legal geek, so I cannot base my position on jurisprudence or any legal theory, but I can argue from historical evidence which shows that the government cannot be trusted respect our privacy. The illegal and unconstitutional tapping of emails revealed by whistleblower Edwards Snowden is proof of that.
As Cook argued, the FBI’s petition has consequences that far overreach this particular case. As I understood, it would basically give government access to the data stored in every iPhone in the world, a power we know it cannot be trusted with. Should this considerations play no role in Apple’s decision not to give into the FBI’s petitions?
