Earlier quoted context omitted.
We really need these things to be Closed Circuit by law. Want the data? Get a warrant and seize the device physically. Centralized databases of surveillance information needs to be outlawed criminally.
Warrants are extremely easy to get, basically rubber stamped. It's so bad that LE will put in things they know are outright unconstitutional, knowing the magistrate won't really read it or care about citizen's rights.
It's the difference between surveillance and mass surveillance. The latter is the bigger problem and warrants will solve it.
