I call it "going through the motions of science" in order to be able to claim scientific objectivity.
There certainly is a science of forensics, but I think that what happens in a crime lab relates to that science like plumbing relates to hydrodynamics: it's technology, not science.
Done right, this technology leads to results that are generally more reliable than eyewitnesses and other forms of circumstantial evidence. But it's a mistake to consider a technology infallible just because it's based on science. The Scientific Method cannot rule out accident, human error, and malice.
