This thing has millions of views. We don’t have the resources to arrest everyone that saw it, nor should the law and courts be swamped with attempts to over something made by willing teens being stupid.
The authorities should certainly try to track down the major propagators of the video and prosecute them.
I think this kind of thing is payback for our own permissiveness. Those of us who patronize even R-rated movies and cable channels with dirty bits have helped coarsen the culture and sexualize the children of irresponsible parents.
