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.

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.
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...
