[Scan-DC] Secret US spy program targeted Americans' cellphones

[Greg Danes]

I found this link very interesting as I am sure it cuts both ways in send
and receive. I would think a tethered blimp at 1000 ft. with directional
antennas would be a better bet to scarfing up cell phone info since you do
not have the Doppler effect per se, FAA in-flight rules and other
hindrances. The other thing is a cell phone can be bought in any drugstore
for 20.00 as a throw-away. Use it once in one location or even twice and
toss it in the garbage and buy another one with a different IMEI number and
card. What would be the point of having data on a phone bought anomalously
in a CVS and tossed into a dumpster?
