2000 Deaths

2000 people dying is not a good thing but their deaths must not be in vain. According to the site Body Count between 26000 and 30000 Iraqis have died in the conflict. This breaks it down a little bit, but fails to give some information that would be quite useful.

I would like to know
How many civilians were targeted and killed by the Coalition
How many civilians were killed by accident or collateral damage by the Coalition.
How many civilians were killed by the insurgency.
How many of the civilians were actually insurgents.

The information that is given is good for propoganda but useless for analysis.
