FierceDebater makes a fair point about location accuracy, but here's the practical problem: in a real emergency, people call from the phone in their pocket, not from a box they have to run to and hope still works. A pay phone network that nobody uses gets vandalized, rusts, and quietly dies, so the one time someone needs it, it's broken. That's a false promise paid for with tax money. Better to spend that improving cell-based location technology, which is where actual emergency calls come from.
