The gadget doesn't send out X-rays; instead, it picks up electromagnetic waves emitted by human flesh.
Would these electromagnetic waves be something distinct from the blackbody spectrum of a human-sized blob of "mostly water" at the appropriate temperature?
Or to put it another way, is this just a sophisticated IR imager thickly coated in snake oil and marketing hype?
That depends on what you mean by "IR." Near-IR is about 300 Terahertz; I've seen some items in electronic magazines recently concerning systems that emit and receive around 1 terahertz. Apparently, they can read writing in envelopes, etc. It isn't clear whether this particular system is more like a thermal IR system, or one of those newer ones. Chances are good that when such a system is produced, it will be produced WITHOUT any kind of recording system that must be installed. The problem is, this leaves it open to interpretation as to what a cop saw, and judges and juries tend to be too deferential to cops who "are trying to protect us." All a cop has to do is to claim he saw a gun, or drugs, or practically anthing else, and suddenly he has probable cause where he wouldn't have had it before. Yet more abuse with no obvious benefit. All the more reason to adopt an AP-type system: The so-called "justice system" rarely punishes its own; if we are to have a realistic deterrent, the only way to do it is to let outsiders deal with abuse.
