I think there were probably considerable Red Teams and all sorts of analysis done. I am certain that some segments of the Intel Community never lost focus.

In general though, I think the common political narratives thrown about in the media hampered how analysis was done; whether it be WMD in Iraq, Bin Laden in a Cave, or if you are in the U.S. the famous "DC Sniper might be in a White Box Truck". In these cases, narratives designed to give the populace comfort result in analysis being skewed to find that which has been declared rather than sticking to structured analytical approaches and hard data.

I was just thinking about it last night, the perceptions placed in my mind and others and how that can really hinder long run objectives.
