The inspector general certainly played a useful role. I have no particular opinion on the system—once again: one committee, several committees, how to divide oversight roles—other than to say that all the agencies working in the field should be monitored. If all the departments are monitored, there can then be different system models that are more or less effective and more or less costly. However, if all departments are subject to actual and serious oversight, I think that would be satisfactory.
