Not sure where they'll go with it, but it's good that my local Metro is focusing on unsolved murders. One conceit of some cop shows is that there's some immense pressure - from above, from the media - to close cases. Locally there really isn't, at least from the media. I have no idea if the cops are allocating resources to such things appropriately, but the idea that there's usually intense outside pressure for them to solve crimes is absurd.
A young guy was killed around the corner from me a couple of months ago and his death barely got a mention. I've seen nothing about the investigation.
