And how do you know that action isn't taking place inside those houses with the porch lights on? Maybe a mother is online searching for a safe house for her and her child. Maybe a father is finding a shelter to donate to. Perhaps a couple is looking at foster care. And a neighbor asks why the lights are on, and conversation begins. Maybe, just maybe, one or two or ten or a hundred kids will be safer because someone turned on CNN, or logged in to facebook, or atoz, or left their porch light on. Or would it be preferable to leave the lights off? I don't know how we'll ever know.
