That is a strong argument but I'd like to play devils advocate for a second.

First, "unreasonable" is a key word. Is the copying of data without any noticeable inconvenience to the citizen considered unreasonable? Another key word would be "seized", is copying considered seizing? Seizing is legally defined as the removal of property, one might argue that no seizure was ever made during this wiretapping.

Second, the Bill of Rights was written over 200 years ago. During that time PHYSICAL searches and property seizures were the primary concern. Nobody could even fathom the concept of the Internet or the role it would play in today's society.
