Question: do the hacker/home-DNA labs allow for the ability to take someone's DNA, amplify or recreate it, then allow you to smear it on a jacket or a dead person's cheek, thereby framing an innocent person?
But A) naked DNA will be exposed to the elements/chemicals which could cause damage/denaturation, B) it would look really odd to find batches of pure DNA without any hairs/cells/other proteins.
Maybe some techniques exist to replicate more believable tissue? Honestly not sure as I'm not too well versed on lab-techniques other than sequencing.
