"Wiretapping of email is delicate for two reasons. First, lawmakers have not yet defined rules that make sense in the online world….
Second, the information available online is astonishingly comprehensive. We talk about wiretapping because the principle is as old as eavesdropping on telephone calls, but the wire is an inadequate image. Online surveillance is not much like listening to an ephemeral conversation. It is about accessing a vast mine of electronic data. All the information that currently enjoys legal protection – relating to our health, finances and communications – is increasingly discoverable online."
