Japan had a problem some years back from people committing suicide jumping in front of the Shinkansen (bullet trains) to do so. It mostly ended when they started to charge the family for the cleanup and disruption to the rail system. It is not inconsequential charges either.

The difference is the Japanese have some family and personal pride and some degree of self respect, which is missing in most of the valley trash problem population. In many cases the parents are just as bad if not worse than the offspring.  Their names are next to their offspring on the welfare roll (or cell block roster). Can't squeeze blood out of that turnip. 

But we can cut off PFD's,  all social services and issue a Blue ticket to the entire family of repeat miscreants.  Soylent green from those who remain.
