It's not easy, and it's very expensive.http://areyoutargeted.com/2011/01/what-constitutes-evidence-of-electronic-harassment/An invisible crime, committed at the speed of light
When a person is shot with a gun, there are mountains of evidence left behind:
* the bullet, enabling investigators to narrow down the search for the weapon considerably;
* the entry/exit wounds;
* evidence placing the victim at a specific location when he was shot – blood droplets, footprints, and clothing fibers;
* ballistic evidence, allowing the bullet to be traced back to its source with some reliability;
* evidence left on the bullet itself – barrel markings, DNA of the suspect, and the suspect’s fingerprints (even if they’ve been wiped off);
* a loud noise, alerting bystanders that a crime has been committed, in real time;
* and more, depending on the circumstances.
However, let’s suppose a person is attacked electromagnetically. What evidence is left behind?
* The target’s uncorroborated account of the sensations he felt.
The attack itself is completely silent and invisible. The attacker could be miles away. The equipment used is unknown, and effectively untraceable. There might be no visible or identifiable marks on the victim, as emerging nonlethal weapon (NLW) technologies are intended to inflict intolerable pain on a target, rather than damage him.
