March 16 US drones tracking Mexico gangs

The American authority have outlawed drone warfare on homeland soil but quietly approved its use for tracking criminal gangs into south america. The sound produced is imperceptible, a low drone resonating at such a frequency that even two to three minutes exposure causes the white and red blood cells to vibrate at different rates due to their relative densities. They intend to send it out in the dead space in the cell phone signals, those pings back and forth used for sms messages. That's the art in the operation : the drone senders need to be absolutely sure who is using the phone at any one moment. It starts at midnight and it shouldn't be too long before we know what happens.
