Just read this. Beat me to it.

“To the best of our knowledge, we did everything we should have done,” the statement read.” – The Univ of Colorado

So James Holmes sent a notebook to the Univ. of Colorado detailing his murder spree. This is the above quote they had after being asked if they had “knew” of anything. My thought is that this was probably delivered, they wrote it off, it happened and now they are covering it up. In 2012, this seems more likely with this kind of statement.
