Faking DNA

DNA, the veritable gold standard for evidence in criminal cases, can be faked! Scientists in Israel have demonstrated fabricated DNA evidence, specifically in blood and saliva samples. With access to a DNA database they can construct a sample to match a DNA profile without obtaining tissue from that person. And these same scientists say the process is simple enough that any biology undergrad could replicate it. This coupled with the fact that DNA evidence is easier to plant at a crime scene than a fingerprint, is enough to give this person (me) pause. At this point in time it appears that criminologists and investigators aren't worried because they think the technology is still beyond the reach of common criminals. I wonder how long before that changes and then how many cases will have to be overturned whether or not the person or persons were actually guilty of criminal acts.
