It starts to get good halfway down: I downloaded Neighbors—you can do so without owning a Ring doorbell—and plugged in my address in boring Arlington, Massachusetts, a city of 45,000 that recorded zero murders and only seven robberies last year. It decided I needed to know that someone in the uniform of a local lawn-care service had recently knocked on someone’s door instead of using the doorbell and, when no one answered, left. Also, there was a building fire two towns away, a couple of days ago. Also, two young people, one male, one female, wearing identical T-shirts and lanyards with name badges, carrying clipboards—likely trying to get signatures for some cause or another—rang a doorbell and then walked away when no one answered. “Anyone know who they are?” the post from a Neighbors user asked, perhaps concerned about Islamic State infiltration of the Boston suburbs. “Call the police,” one helpful commenter replied.
