&gt;There are methods to detect a tail, so you could employ them and then not go to the secret place until there is no one watching. To maintain &quot;technological neutrality&quot; it would require there to exist equivalent digital methods for people to use to prevent being observed.<p>Honestly Tor seems like a great analogy here. It makes it far more difficult to be observed, but it&#x27;s fallible, as is trying to spot a tail.
