Why would having a database of people who have gone missing in national parks and bureau of land management land be useful?

Someone asked me that question.

At first I was very surprised (that's a question that needs to be asked?) and questioned the future of humanity. I am beginning to think the reason there is no list isn't because of the national parks service, but because people just go along with whatever is happening and seem to be sceptical and dismissive of anything that deviates from what they're used to.

But it is probably a relevant question and something important to have answers to. Not everyone really understands Missing 411 well like some people here do, and it is something that seems easy to explain at first glance and only becomes more compelling after you understand the details.

So I thought I would ask here so I can link that person to what you write.
