My view on the key concepts (keywords italicized):

• I think the goal needs to be something palpable, instead of vague and abstract. At the end of this all, we need a physical document of all the evidence.
• This document needs to contain only hard evidence that is sourced and has been thoroughly vetted by the community in a scientific quality.
• The subjects of the evidence need to be concrete organizations and individuals that can be prosecuted, as opposed to ideas and movements that cannot.
• We need to be concerned with child trafficking on the systematic level, if the big players are down the small players will follow.

I've come up with the most concise and focused goal definition I could that contains all the important concepts:

To gather, source, and organize a body of hard evidence against the players of the global child trafficking system, in the form of a single end document that can be confidently used to pursue their prosecution.

I'm sure this is not 100% perfect, and since we should work as a peer-review system, I encourage you to start a discussion under this comment, and I'll keep the comment updated.

Edit #1: Changed focus to child trafficking from broader human trafficking. Added focus on prosecution.
