Yeah, that's the outer bound of technology. That decision was made difficult because standing on public property and looking in a window is not a 4A violation. But, that tech is SO advanced that it made an absurdity of actual real walls.
The same cannot be said of clothing. At least not yet.
Also, probably worth clarifying that I'm not predicting that this will be free of legal issues. Heck, a court somewhere might say this is more like the imaging tech in Kyllo. I'm just saying that this is not a legally cut and dry situation.
Post-Heller, this is on a long list of things that will have to be resolved.
When we go out in public, we are giving up a great number of privacy rights. The "expectation of privacy" is almost zero.
I recall in the 90s there was a video camera that had an IR lens or something that was so sensitive it could "see" through artificial fabric/materials like spandex. I can't remember what happened with that, but I don't think it was an LEO issue.
Yes. But there is some degree.
If I go in public, with my social security card in my wallet, I expect that it being in my wallet would make it private.
