I think justice was served in the Knox case (I read Italian, but I did not care to read about the case from the Italian perspective because of the pritzus involved) and at least the soap opera is on its way to a well-deserved end. In any case, it isn’t our inyan except that:
What can we learn from the case?
Sheloi, sheloi asani goy…………ich bin shtultz tzi zan a Yid!
The way that whole crowd lives is baruch Hashem so foreign to our ways, and we need to always make sure we understand what “sheloi asani goy” and “vehaya machanecha kodoish” mean.
If that means sending oisvorfen who have gone OTD and live like Knox and Soleccito and Kerchner did far, far away, that is the price we need to pay to make sure that this kind of behavior is never, ever seen as even remotely normal in our world.
