I read the article, and it didn't mention any of these things. It didn't mention re-education camps, or even arrests (or even prosecutions). It also didn't mention scanning internet postings. It suggested the technology might be used at immigration, and hinted it was related to pupil dilation, and heart rate/blood pressure. Presumably to indicate who should get a more thorough inspection? It certainly didn't even suggest that anybody would be arrested based on this test, nor that it was foolproof or even accurate.
Of course, I fully understand that even that might be too much for those of a libertarian bent, but it still didn't mention any of the horror stories you just made up there. It certainly didn't suggest anything even remotely related to thought crimes. Did it?
Maybe you should post the quote that gave you the impression this had anything to do with thought crimes. That way I can see what I missed.
