I have looked at an internet translation of the VEJA article that marciovp refers to, (thanks marcio) and if I understand it correctly the thrust of the briefing (Brigadier General Kersul, during the reading of the dialogues of the pilots of the A320 of the TAM in the CPI of the Aerial Apagão) is as follows...
There is no evidence of technical malfunction...
An air transportation system cannot ignore the possibility that pilots will make some mistakes...
Aircraft should have warning systems to alert the pilot to his mistakes..
The TAM A320 did not have an efficient warning system for this mistake...
Nor did the runway used offer some safety margin..
Progress.
