Fabricating DNA Evidence is Possible
The NY Times recently reported that the gold standard of proof in all criminal cases “DNA” can in fact be fabricated.
Apparently it is possible to create fake blood and saliva samples containing DNA from a person other than the donor, using a standard technique called whole genome amplification.
And, to take it a step further, it is also possible to construct a sample of DNA to match someone’s profile without obtaining any physical tissue from that person.
The latter relies on having access to the DNA profiles stored in law enforcement databases. Our DNA is stored as “a series of numbers and letters corresponding to variations at 13 spots in a person’s genome. Scientists can clone tiny DNA snippets representing the common variants at each spot, creating a library of such snippets.” One can then “prepare a phony DNA sample matching any profile by mixing the proper snippets together.” [science.slashdot.org]
That is startling. Do you believe that a more in depth method of DNA analysis might be used in the future to prevent fake DNA evidence? Such as looking for specific genes of a person?
Well, if ones go that far just to frame someone he can actually find easier just follow and steal some dna sample.
