LOL. The idea of the local cops using Van Eck phreaking or NIC vibration signatures. These guys have enough trouble using wire taps for Christ's sake.Ok, I admit it's possible. And that just because you use equipment doesn't mean you need to understand why/how it works. But still...Anyway, the defenses are trivially easy to implement against such things, even places like banks or embassies do it (not that it helps if all the bars and restaurants in a certain radius are bugged, ha!).1. Obtain a cheap Chinese NIC with cash or rip one out of a second hand computer from a garage sale.2. Turn a room into, or easier still, put a protective Faraday cage over your hardware. For people who were asleep in physics, replace Faraday cage with "metal box". e.g. Trash can.Ta da!
