The idea of an injury test doesn't mean we're recommending that it be disclosed. You have to recall that in a changing world we have information in the hands of government here that has been provided in confidence by governments that no longer exist. How do you ever get that information released under the current provision, with no discretion and no injury test?
Injury tests and discretionary exemptions only allow you to take into account the circumstances and the times. They still allow you to keep secrets, if the circumstance and the time require it.
