there are lots of places taxoayer pay for which never see the light of day. i thimk ultimately though, this is not atall about that. they have very lenghty projects to get to root causes of issues. before such a project is fully completed and signed off on, they will not sah a word. before they have all the answers, you will get none. places of science -generally- work like this. no poitin bringing out incomplete information or uncertainties especially in siluch a place which faces a lot of public scruitiny.
