I think that we are getting deeper into the woods and Supreme Court can actually keep two opposing concepts in mind at the time and be ok with it. Supreme court decision covers police and says that police cannot spy on cellphone owners.
Can somebody explain, if, then NSA, FBI, CIA, DHS, TSA, DIA and thousands of other agencies can continue spying? What if policeman will call his colleague at DEA, FBI and will ask for data: happens all the times. What about the usual process, where DIA employee working with NSA data while spying on US people will give a tip to local police to check "that person".
Also, does the ruling cover only cellphones? What about the rest of devices, such as desktops, tablets etc. Ruling says that other devices are covered.
The outcome is that spying and collection will continue as it has continued. People who have privacy concerns will be pacified with this ruling.
Finest example of doublespeak and doublethink.
