That draft is about IPv4.  If a border was crossed the child 
abduction [1] would be a matter involving more than one 
country.  There are already border controls in place to collect 
information.  I don't think that it is possible to have armed robbery 
over a communications link.

There is a short discussion related to the above in Appendix C of
