A few weeks ago, three students at Milken Community Jewish High School in Los Angeles were expelled for making a sexually explicit video of themselves that was eventually seen by members of the student community. Many parents and teachers in the Jewish community have expressed confusion at how educated Jewish students at a school like Milken did what they did.

But to think that what happened at Milken is isolated to the particulars of the parent-child relationships of the families involved is myopic — and too easy. To be sure, such behavior is not widespread in our children\’s communities. But we can be relatively certain that for every incident brought to light, many more are hidden in the shadows.
