This really does get to the point where I see only these possibilities: (1) Brooks et al really didn't know what was going on at the time due to incompetence, (a) innate; or (b) innate and exacerbated by massive quantities of cocaine. (2) They knew what was going on and thought it was a good idea, due to evil stupidity, (a) innate; or (b) innate plus the coke hoovering. Believing in the essential goodness of mankind, I bet on 1(b).
