Larry, Where do you get that the FBI laboratory ran multiple tests with CE-139 that yielded positive reactions?
I didn't say CE-139. Their tests used a similar rifle and ammunition.
However, after reading your post again, I noticed that there were multile tests ran with CE-139, yet only mention the negative reaction results. It appears that their first test yeilded positive. Contrived? Hmmm.
"We fired the rifle[CE-139]. Mr. Killion fired it [CE-139] three times rapidly, using similar ammunition to that used in the assassination. We reran the tests both on the cheek and both hands. This time we got a negative reaction on all casts."
