A law must be enforceable, otherwise it is useless. A law for wiretapping voice phones is enforceable, because only few criminals have the capability to build their own hardware encryption devices for secure real-time voice scrambling. A law for wiretapping into text chat software is not enforceable, because anyone halfway skilled in cryptography can produce his own encryption layer on top of the wiretapped text chat. The worst inconvenience a criminal would suffer from such a law is that they would need to use the copy&paste function of their device. A law that by design is not enforceable, serves no reasonable purpose.
