No offense meant to any army people here, but the 82nd is not a police/para-military-type force. The purpose of this kind of unit is to use maximum force in order to attain their goal. An elite unit, yes, but not trained for operating around civilians.
I recall reading about the first visit of the 82nd to Afghanistan - there were complaints about them being Rambos towards civilians.
The way I see it, it is not much use criticising the 82nd for doing what they were trained to do. USA does not have a para-military force, and that could have been one reason why Iraq descended into chaos. Military units are unfit for police-type tasks.
Now the question arises, what kind of troops would be needed for asymmetrical warfare? A combination of SWAT, peace-keepers and rebuilding/construction/humanitarian forces?
