A friend of mine, let’s call him “Jim”, was recently in neighborhood park in a wealthy Midwestern suburb with his two boys, age 2-3. It was warm and there was a fountain so the kids do what they like to do in such weather, i.e., take off all of their clothes and splash around in the fountain. Jim pulled out his video camera to capture the charming frolicsome scene. Two police cars quickly converged on the scene and the cops held Jim for 45 minutes of questioning. Was he sexually exploiting his children? They never doubted that the kids were his, so their only real question was whether he had chosen to make his exploitative films in a public park, in full view of a bunch of houses, rather than in his own backyard (real criminals hate to do their work in private, apparently).
Fortunately, Jim had recently watched this helpful instructional video, and therefore things did not progress to the next step, which the cops helpfully explained: they would take the kids and put them into “protective custody” (i.e., farm them out to foster parents who would be paid thousands of dollars to keep them in their double-wide trailer with almost no supervision by the state). Jim and his wife could then hire a lawyer and attempt to get their children back.
The saddest thing about this incident is that everyone involved was white and nobody was a Harvard professor. Therefore there will be no beers at the White House.
[Tried to find some background on what could actually be illegal about making such a video. I found a 2000 article about still photos at Salon.com. The next relevant article was also on salon.com, a first-person account by a father accused by a drugstore photo clerk. It seems as though it is a “we [civil servants] know it when we see it” situation.]
