Indeed.

How might people suggest that this would work, do you suppose?

"We've narrowed the victim's location down to one city block, boys! Assemble a posse and start knocking on doors: If they don't answer, kick it in!" ?

(And before anyone says "Well, it can work however it used to work!" please remember: Previously, we had landline phones in our homes. When we called 0118 999 881 999 119 725 3 for emergency services, there was a database that linked the landline to a street address and [if applicable] unit.

That doesn't work anymore because, broadly-speaking, we now have pocket supercomputers instead of landlines.)
