For folks wondering why this is on HN, there's some interesting info in the middle of the article about the tech the new police force are using in Camden: "There are 35 microphones planted around the city that can instantly detect the exact location of a gunshot down to a few meters (and just as instantly train cameras on escape routes)."

Yeah, that's more hype than reality. Those gunshot detectors work 'ok' not perfect. And they don't have enough detectors or cameras for anything other than the most basic coverage.

"For folks wondering why this is on HN" I'm glad it is. There are (much) bigger problems in the world than growth hacking and nginx performance. There are many bright people here, it'd be a waste if important issues like these weren't discussed in this forum.

  And there are countless forums to discuss such "important" issues. Just because a story has humanistic touch, that doesn't mean it belongs here.

    You don't need to read it if you are not interested. I'm a tech guy and I found it very interesting to read.

Don't upvote it if you don't want to see it. That's all. That's how it works.

  That's also how reddit works, and in 6 years it's gone from technology, programming and world news to memes and cat pictures. When anyone can create an account and start voting, both moderation and reminders from existing users about appropriate content are needed to prevent or slow the move from specialized articles to general interest timewasters. It happened to digg and reddit, I'm perfectly happy with people voicing concerns where appropriate to prevent HN from just becoming another reddit/digg/fark/somethingawful/thechive

    Per your statement, how does this article cluster any less with "technology & programming" than the "world news" category you mentioned? There have long been articles dealing with sociological and economic realities of our time on HN.

I wonder if they could do the same thing for the sound of breaking glass? That would probably indicate a crime or at least an accident.

  I'm sure you could. I have glass break sensors throughout my home to detect someone entering through a window.
