This petition serves no useful purpose and is backward-looking to say the least.
It seems to be labouring under the assumption that nothing has moved forward since 2007.
Everybody else is living in the here and now and are progressing methods using technology and exchange of information between international policing authorities for now and in the future.
Investigation into the exploitation of children is of paramount importance.
For example, in Portugal the PJ are at the front of these (and other) developments as can be seen by the reopening of Madeleine’s case.
I refer you to just one document outlining one current activity.

http://en.wikipedia.org/wiki/AMBER_AlertIt would be excellent if the energies devoted to hounding the McCanns were redirected to doing something useful which would be of benefit for a change … just one example might be a petition deploring child poverty and the resultant effects of life choices for many children in this country.
If that one doesn't appeal I'm sure there are many other causes crying out for attention and support. Hounding the family of a missing child doesn't fit the category as decent people consider that to be beyond the pale.
