I find a couple of things very disturbing in this article. At the surface it is what all of us should find disturbing and that is a clear violation of the 4th amendment. The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. Next, lets look at a quote from the article: “If something is obstructing the flow of radiation, for example a weapon, the device will highlight that object.” The "flow of radiation"? They are talking about terahertz radiation being blasted at you from a distance. There have not been any studies on the effects of such radiation but A study published in 2010 and conducted by Boian S. Alexandrov created mathematical models predicting how terahertz radiation would interact with double-stranded DNA, showing that, even though involved forces seem to be tiny, nonlinear resonances (although much less likely to form than less-powerful common resonances) could allow terahertz waves to "unzip" double-stranded DNA, creating bubbles in the double strand that could significantly interfere with processes such as gene expression and DNA replication". This was just a model but there is no conclusive evidence showing it is safe either. Lastly I find this quote disturbing: “The technology is going to get there,” Kelly said, adding that he is pleased with the progress made in the last year. Yeah, I bet he is pleased...
