<div dir="ltr"><div>I think there are significant principles in here, maybe on everybody's mind but not called out specifically: if data is made available to the public, rather than made available only to the police, it's much more palatable. In either case, it's important that individual privacy not be infringed beyond some certain point. If all the data is public (and presented in a way that is structured & useful to the public,not some PDF report) then it's easier for everybody to see whether it is done in a way that respects individual privacy in appropriate ways.<br>

i can't tell if you replied to the list or just privately to me.<br>

that sounds like it would be fun, but it would be more worthwhile if there were a larger goal to be accomplished, ideally with funding.<br>
<br>
it wouldn't be trivial - what is the right way to record timestamps onto an audio recording from a GPS? perhaps use one of the two audio channels as a SMPTE timing track? that's kinda ridiculous but there's probably lots of code already written...<br>

what do people think of the shotspotter system installed in oakland?<br>
<br>
it's a network of microphones on telephone poles, each with a GPS (for<br>
a precise clock) and a network connection. When a gunshot-like sound is<br>
detected, they send the sound and its precise timing to a central server<br>
that determines the location of the shot, and tells the police to go<br>
there.<br>
<br>
some people have expressed concern that the microphones are used to spy on<br>
people, but it would be impossible to hear a conversation from the top of<br>
a telephone pole that wasnt already loud enough to be heard inside nearby<br>
houses (or the phone in your pocket).<br>
<br>
apparently the city pays $264,000 per year to keep shotspotter going. I<br>
think sudoroom people could do it for much less if they thought it was a<br>
useful thing. They would be discontinuing it to save money, or perhaps to<br>
avoid having to send cops to do actual work once in a while...<br>
<br>
i mean.. sending police toward the gunfire? sounds like a good idea...<br>
