Faking DNA Evidence

It apparently is not that difficult to do. If the lab has the DNA profile of the suspect (not even an actual sample, just the profile), they can make the test results match the profile.

Since there has been no shortage of crime labs that have skewed or even faked tests to "prove" the guilt of people that the cops wanted to convict (the FBI and Texas crime labs come readily to mind), this should be a serious concern.

I remember that there was a cop-killing in Boston about 20 years ago; the cops were so sure they had their man, but the physican evidence was lacking, so they transferred his fingerprint onto the weapon. The defense expert spotted it and the jury acquitted him.

Eyewitness testimony is malleable, witnesses lie, physical evidence can be forged. On the other side, there is witness intimidation and experts for hire.

So who do you believe?
