Who are they polling? I think there's a fairly limited amount of people who would really want this, and lot of people who wouldn't.

You need to live in a city, but not in an apartment building, which is a pretty small (and wealthy) proportion of people. If you live in the suburbs or the country, you probably don't mind leaving packages on the porch. In the city if you don't have a doorman, a package is almost guaranteed to get stolen.

Homicidal maniacs who want to kill total strangers for no reason are pretty rare. Packages thieves are ubiquitous.
