You could keep a burner phone in your car with one of those location tracking apps. If it was stolen, you could give the police the location in real time, like that LoJack device used to. Valuable items that are difficult and expensive to replace. Especially if it’s how you earn a living. That would be a tough situation to be in, coming across someone carrying your stuff in the street.
I was listening to an analysis of the arguments and the jist here was that a crowded city, because of higher crime, has a greater need for allowing citizens to arm themselves for protection.
