รฆtherial or to catch a thief

Technologically savvy forensics experts in Germany (the broadcast is only in German) see great potential in exploiting inchoate but measurable aberrations in the environment—specifically the electromagnetic fields generated in any indoors area by electrical sockets.  The not completely hypothetical situation that researchers hope to stage and test the refinement of their gauges involves the story of a murder most-foul.  A woman has been killed, the experiment supposes, and in the absence of any physical evidence, damning or exonerating, the investigators have no way to eliminate or prosecute one of the suspects over the other, the woman’s husband or their neighbor.

Screams and a struggle, without corroboration, however do not go without an audible-footprint, at least indirectly—thanks to the unique and indelible cycling of electricity delivered over alternating current, there’s a time-stamp running in the background of any audio or video recording—that can pinpoint when and where the recording was made and if it was edited, no matter how cleverly or professionally done.  While Big Foot and UFOs are not necessarily in the vicinity of AC power sources, informants and confidential sources usually are and governments are hoping to be able to catch whistle-blowers in the act.  So much for crime-solving, but the poor woman’s death was not captured by any means—conventional at least, but supposing the attacker carried on his person some sort of electronic device, that electric hum would echo in a complimentary way to the method of exposing a snitch.  Though any change or disruption power would be infinitesimally small, one’s devices and electronic accessories can also be exploited, like seismographs, picking up any change in the electromagnet landscape.  Even though the mobile phone forgotten (given that that cell-phone is not already tattling or building an alibi in other ways) in the attacker’s pocket derives no charge from the electricity lurking in the wall socket, via induction, that external power source disrupts the phone’s internal current, in tiny but telling ways, and imprinting the signature of one’s whereabouts at any given time.  Atoms are judged to be perfectly elastic, capable of forever bouncing off one another without drag one experiences on the macroscopic level, but there are certain tell-tale stress-marks that have to do with the optimal, most efficient alignment of a wire in a circuit. While these are not measurable performance-metrics at the moment—that we know of, and exceedingly small it looks like such static might be of vital interest in the near future.
