It just looks like they have a lot of money is all. People keep saying they're under funded but then link to a page that says they have almost a billion dollars per year. Much more than any other civic institution I can find info about. How much funding would it take for them to pursue suspicious deaths? What else are they doing that they don't have resources for this? Maybe the problem isn't funding.
