Ahhhh yessssss. The dangers of the TV News "roll-as-you-go" door knock!
Take a watch and listen.....
IF you're going to do these kinds of things, avoid even the hint of trespassing by parking the photog on the sidewalk, the street or other "public" place, not on a person's porch, driveway, or front lawn. If I remember correctly, there's a thing on the camera lens called a "zoom". Use it!
I bet they might have gotten the crazy ol' coot to talk if she hadn't opened her door and seen the photog on her own stoop!
