Rest In Pieces

From what I recall more or less what Sun Zi (Sun Tzu) recommended 2500 years ago.

AP Sensing shows me a video of a man walking across a lawn before lifting up a rifle and firing it during a test. A fibre optic cable buried in the ground a few metres away picked up the whole sequence.

“You see every single footstep,” says Clemens Pohl, chief executive, as he points to a chart revealing disturbances in the fibre optic signal. The footsteps appear as brief blips or lines and the gunshot as a larger splodge.

So… we just covered all of our cities in a(nother) sensing network? Cool, cool. Alexa order me some tinfoil.
