Legal/constitutional is the only difference that really matters. The tech is globally available to anyone. The law determines how it may be used. Overall I think mass surveillance and other cyber-intrusions into civil liberties can only be realistically solved by legislation. It's far too easy to spy on a people who insist on carrying around little location-aware transponders and posting all their activities to the Internet. It's legislation that limits this, and much more importantly limits what it's legal for the government or private actors to do with this information.
