Day 7 of 180: Is the loss of privacy in ‘Tag’ too far fetched?

Obviously I don’t think so, and neither does the US Supreme Court.

In GPS case, US court debates ‘1984’ scenario

Basically this is a crude form of Tag. Your phone is a GPS, transmitter and receiver. How long before police don’t need a warrant to track that… already done.
The relevant “Tag” part – “The surveillance system has been procured by the Metropolitan police from Leeds-based company Datong plc, which counts the US Secret Service, the Ministry of Defence and regimes in the Middle East among its customers. Strictly classified under government protocol as “Listed X”, it can emit a signal over an area of up to an estimated 10 sq km, forcing hundreds of mobile phones per minute to release their unique IMSI and IMEI identity codes, which can be used to track a person’s movements in real time.”

Far fetched, hmm, I don’t think so.
