Regarding the court cases, I literally included the entire linked info for one of those Court cases in the post you're responding to. For both of the cases, the verbal exchange was at the same time as the shooting. In the other case, the victim verbally identifies the person about to murder them just before they were murdered. The argument that shotspotter is a wiretap falls apart under the slightest bit of scrutiny and there's no way the legislature meant to protect the right of people to be free from audio recording while shooting someone in public.
