Yes, imagine, we even have the right not to be spied upon by the USA. Yes, funny enough, the NSA spying on foreigners is of course a violation of the 4th amendment, unless "...upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized."
Wholesale surveillance neither qualifies for "probable cause", nor for "particularly".
Yeah, I can tell you how this would work. If woke up by chance an noticed that bugger of a robot trying to brute force my phone, I'd fry him with some live wires.
After that, I get arrested and dragged to a court, for "destruction of government property", and the judge explains me that the intrusion is not a violation of privacy, since it's a robot and not a human being, and also that what the robot did does not require a warrant, since no human will be looking at the contents of the phone, or use the PIN, and that I will only have any standing when some human eventually decides to have a look at the material. That fact will also be classified.
