Wow there are microphones used to detect gunshots in Chicago? I remember seeing such technology in a relatively obscure cyberpunk comic book when I was a kid, but I never thought this would be legal.

Do the microphones record conversations too? Can the government spy on its own citizens? I guess some secret court ( https://en.m.wikipedia.org/wiki/United_States_Foreign_Intell... ) allowed it?

Oh boy, wait until you learn it’s not just Chicago where they deploy this crap [1]

There are LED street lights in San Diego California that do just that. They have cameras and microphones. The microphones are used for Machine Learning of what people say. [1] There are a handful of other cities deploying these. It is a clever way to deploy CCTV much like what the UK has but without drawing much attention to it.
