Perhaps such interception capabilities were developed because encryption technology wasn't widely available at the time. Even back then people with high security needs encrypted phone calls with contemporary encryption technology. Times have changed and encryption technology is widely available now. The question is whether encryption will be broken by people resisting change or whether law enforcement will be satisfied with metadata alone. EDIT: Should have been posted under grandparent.
