// Anne, if you read everything about him you'll see that he ....... have been properly investigated long ago.//
might/coulda/ and so on
ish - "never forget in a good going cack up, the role of sheer incompetence" anonymous British Army officer ( and blumey he should know!)
ALSO fulfils the swizz cheese model of screw-ups ( once the darling of safety theorists ) - a chance was missed a few years ago, another chance was missed when he was reported for flashing, achance missed when his colleagues didnt report his rather heterodox views on girls - - - just like the holes in a swiss cheese which have lined up
Another is an unsafe soil bed(A) in which an unsafe sequence will take root and grow (B) - here A is the failure to report his emails and B is his offending behaviour
and .... depending on the model you adopt, the measures to combat are different ( golly the knobs who rule us have a difficult life !)
