I really want to convey how not aggressive I am about this. It's sometimes hard in text.
Your point 1, about hasty interrogation. I accept that a hasty interrogation in the field is naturally less safe than one in a controlled environment far away from action. But it doesn't automatically follow that this means torture. Again, see Mackey.
The second quote is interesting, in that yes appointing certain officials can be indicative. However, it doesn't automatically follow that they haven't learned from the mistakes, or aren't aware of the changed atmosphere. Look at the way military innovators work, for example the development of the 'big wing' in the RAF. People went both ways based on tehri experience.
