1. Law enforcement today are more cunning and sneaky than the average police department. The difference is being able to afford high tech technology including ultrasound. Ultrasound is a machine- driven, high- decibal sound-generator that generates sound waves. These sound waves then travel through the air and send back particle readings as they pass through objects. High-density objects produce a more-dense portrait of the object it passes through. For example: when ultrasound passes through antimate objects, it shows the movement of that object. Store security systems no longer depend on cameras as ultrasound generators also identify body-language. If you don't have a record of body-language stored somewhere in a data-base, no problem. Courts can issue a mandate to force someone to follow an exercise regime allowing experts to examine similarities in movement. Then it can be determined whether or not your particle prints are a match .
2. Law enforcement are using these technologies in Traphouses, or SCE - Secure-Contained-Environment where actual people reside .. a home, house, du-plex, trailer house, etc. In these preequipped dwellings have monitoring cameras, audio microphones, panic buttons, recording equipment and whatever else the investigative team deems necessary.
Let's say an individual just happened to know a person residing in one of these dwellings. And say, that person has been on the radar for awhile now and law enforcement officers want to manipulate a move to this...
