I should point something out. As paragraph 2.62 of our report indicates, it was the agency that decided to pursue the verifications in those specific cases. It was the agency, then, that conducted the verifications. In each case, the agency identified problems. It may be a good idea to ask the agency whether more such verifications are possible. That's a question for the agency, since it was the one that conducted all six.
