This is exactly what happens at institutions with blanket licences from Copibec or Access Copyright.  There is no effort put into copyright education, because the blanket licence covers everything!  And of course a publisher would never sue for bad behaviour at an institution with a blanket licence.  Just take the scans down and buy five copies of every book you scanned!  This has absolutely nothing to do with fair dealing.  This is standard copyright ignorance at institutions with a blanket licence.
