First of all, I am not a statistician, so I might be wrong in how I see this...but here goes
Franken calls Hume a liar, but doesn't do any better at answering the question that people really want answered.
Concerned people really want to know if the risk of death to the Americans in Iraq is really much worse than their risk of death if they stayed in the US.
Is Franken, say, comparing death rates per 100,000 among young people (especially men) in California, to death rates per 100,000 among young people serving in Iraq?
The ages of the Americans we choose to compare in Iraq and California should be similar.
So, for example, I think we should compare the chances of death (per 100,000)for, say, 18-21 year old men in the US and in Iraq. Then we should compare the chances of death per 100,000 for 18-21 year old women in the US and Iraq. Then the 21-25 year olds. The 26-30 year olds. And so on.
