#17 - Expert witness: Ten times, and in controlled

[Adam Tyson]

We've talked about D a bit in this thread already, and the short answer is that it doesn't matter what someone else's blood does, because the argument is only about the defendant's blood.

9.3cm2 is less than 9.5cm2, but is it really "much less"? The previous 10 tries were all under 5cm2, so this 11th test is a LOT closer to the target number. Being this close goes a long way to undermining the conclusion, especially since it is so different from all the other data. Is it absolute proof that the witness is wrong? No. Is there some room for discussion about the relative difference in the numbers? Yes. But does this raise at least some doubt about the conclusion? Absolutely, and none of the other answers does anything to hurt the argument.
