I think this case is special in that the source would get the Snowden treatment if the name leaks. If you publish all at once, others can go and verify the details. The source is protected. If you verify pre-publication, e.g., go to the diving school in Florida and ask too many questions, you (and the source) will be under surveillance in no time.
