Re: "near perfect surveillance"
I think negotiations for the people should start with all electronic data is tangible property, as if it was inside a file cabinet in your home, and thus subject to all Constitutional protections.
The fact of the matter is various laws like the Patriot Act and court decisions, like this one, too, have whittled down the Bill of Rights to a hollow and weak shell of it's former self.
This ruling is not a victory in the sense it now appears cell records of less than six days are NOT subject to the 4th amendment at all according to this ruling. Plenty of room for the boys in blue to game. And, they may still get all historical data, because it still exists, so long as it's not used as evidence in a trial.
I haven't read one response from the police industry complaining about this decision. That's a very bad sign too. It suggests they have work arounds already in place.
