and you have to aim a flashlight like a water hose. +1 for the appendix at the end that explains the conceit and lays out the equations used!

One of my favorites, written by John E. Stith.

I think this is the closest analogy I've heard yet, but not in windows on suburban, tree-lined street. People walk down those streets and the windows are at eye level. Someone could accidentally see into those windows. No, I think if we consider windows in hi-rise buildings in a major city, the analogy is getting much closer. Seeing into one of those windows requires a bare minimum of intent and possibly an inexpensive tool, say binoculars or a telescope. However I would be willing to bet that a large portion of hi-rise dwellers do NOT close their blinds on the theory of "No one is looking in MY window."
