alt Hacker NewsThe easy workaround for this (which Flock has used to massive success and why it's drawn so much ire) is to set up or subcontract a private corporation to do this which will inherently be subject to much less stringent oversight. It also allows government and law enforcement to evade accountability.
The legal arguments against Flock are different than the legal arguments against thermal imaging by the police (without a warrant or probably cause). And the latter is closer to the hypothetical broad mind reading (science fiction, again) than it is to Flock.
