Wiretapping predates all of these sort of arguments. Wiretapping was invented at basically the same time that telephones themselves were and was underway for decades before the law even began to take note; the first major legal development in this regard was the Supreme Court saying cops could do it without a warrant in 1928 (they already had been the entire time.)

While that is interesting from a historical perspective, does it inform on the myriad of excuses trotted out for these abuses today?
