And - it sure as HELL isn't just the hooligans being targeted, from the sound of that article. It sure as HELL isn't just noise on the street, either. Part of what they are targeting is 'hardwood floors'.There's nothing in the article to point to this being some super-spy listen-trough-walls technology; all their examples of situations where this will be used are stuff that makes noise *outside*.
The bit about "hard flooring" is from the top five *complaints* to the National Society for Clean Air and Environmental Protection, and "Wooden floors" is part of a quote of the NSCA's spokesperson, Mary Stevens -- background material in both cases; nothing to do with the Westminster Council, for which a mr Steve Harrison speaks in this article.
