This short two-minute segment from ABC discusses the use of small aircraft mounted with faux-cell towers referred to as dirt-boxes to ping devices and identify everyone in range of the flight path. The term dirt-box is interesting since it is likely collecting dirt on random Americans. The military and police even use fake cell towers on land to track people.
So-called conspiracy theorists were ripped on for knowledge of warrantless spying in the USA and have gotten scarcely any recognition for being ahead of the curb. With the advent of smartphones tracking people, listening and using their cameras has reached unprecedented levels of surveillance. Many cell phones have no ability to even remove the battery, the one sure way to know a device is off.
Justifications for sacrificing privacy for security have been layers ranging from rapists and drug users to the endless abstraction of the war on terror. Society is a disturbed and unnatural construct as a result of various forms of oppression and exploitation. A monetary system based on debt insures failures to fester. The lamestream media use of advertising effectively creates a slew of viewers who have a void in their souls they think must be filled with products and pills. Add to that the tendency for control freaks to commit false flags to give further cause for control. Certainly there will be no end of issues in society that can be used promote the validity of these schemes as we approach a complete electronic panopticon. People do change their behavior when being watched nullifying the argument as noted by Glenn Greenwald in this TED Talk "Why privacy matters."
