i can't believe i'm only now seeing this! it's been 4 years and a few months since this talk, and i'm sure it's gone even further by now. i don't even know what to say about it since it's just a novelty at the time of that video. the guy talks about the possibilities for medical purposes and military possibilities came to mind for me(you could image the inside of a building and find out how many people are inside/what they're armed with, etc.) or have the police/fbi/whoever take a "picture" of the inside of a building where hostages are being held, or criminals in general are trying to hole up. i mean the possibilities are fairly endless if this gets off the ground, those are just the ones that came to mind instantly because that kind of stuff has been on my mind since i was like 8 years old XD
