We already have see-through-wall technology, now we have see-in-wall radar. Sprint radar imaging system peeps inside walls, floors to detect bombs. This kind of technology is not really new but what makes this one different is it only needs one side of the wall, unlike X-Ray which needs both side. The radar is able to detect and form a 3D image of the item embedded in walls. Cambridge Consultant is pushing this thing as a security tool, allowing for detection of bombs, drugs, dead bodies, Sprint is currently undergoing testing.
