so, the assessment team never had a formal meeting and never inconvened, thinking they had no control over holmes once he left. >> i think that's a signal that you should intensify your efforts, not walk away. under those circumstances, most well-trained threat assessment teams would have gone into action. >> reporter: but listen to what the university's chancellor claimed early last week. >> to the best of our knowledge, to this point, we did everything that we think we should have done. >> reporter: words under fire now, as those close to the victims now ask, could this all have been prevented? mark greenblatt, abc news, denver. >> we'll have more on this developing story, coming up later today on "good morning america." politics, now.
