“Obama’s fingerprints are all over this.”
I was thinking that literally might be true — fingerprints and/or DNA.
What if he did hold and read some of the documents? Now forensics is capable of doing “touch DNA”. No fluids or blood required. No large amounts of skin under a victim’s fingernails. Just a skin cell after a small touch can provide perfect DNA results.
BTW, I’ve been watching too much I.D. (But the touch DNA is a thing.)
Don't ever look at a fingerprint under a scanning electron microscope (SEM), you'll never eat anything again that anyone has touched without gloves.
