These sources also claim that the blanket was "stolen" by Indians. But these people could be lying about it being stolen. At this point, it looks like to me that the U of Col committee's claim against Churchill on the Fort Clark issue relies very much on the word of the people who claimed the blanket was _stolen_. It is just very possible that an accusation by whites of Indians "stealing" in this time is a lie. If Churchill assumes that they were lying , then he is warranted in hypothesizing that the blanket was given on purpose.
Once the investigating committee accepts that there is reliable evidence that the small pox was spread to the Indians from a blanket that white people had, they are in big trouble in concluding that Churchill is definitely "fabricating" the idea that it was deliberately spread, because of the real possibility that the people were lying that the blanket was stolen.
To try to say it quickly, the investigative committee is unwarranted in reaching such a _definite_ conclusion that Churchill's conclusion is not supported by the evidence. The evidence had does not demonstrate that the small pox was definitely _not_ spread to the Indians on purpose by whites giving them infected blankets. Churchill's conclusions are not as unwarranted or as definitely unwarranted as the investigative committee would have to claim.
