I can see a very near future where such scans

are allowed, but only for already convicted people on probation/parole or in prison. But I really think that the general worry of such scans exposing too much of all peoples private life, will keep them from being used in any other regard (including investigations) than the one I mentioned. I hope, at least. But if not, I wouldn't doubt that a lot of people would start resorting to suicide and/or murder as a way out of that matrix. Not exactly a senario most people want. And so I tend to believe that our culture will not let it happen. Life would surely become worth losing, if it did. Talk about Nazi-like brain experiments......Holy Shit!!
And I really don't think they are as accurate, or reveal as much info, as the scientists claim they do.
