I suppose it falls to me to be the contrarian. Let me start with a point that I hope we can all agree on. Drawing a DNA sample is not the same as taking a fingerprint.
Fingerprints are two-dimensional representations of the physical attributes of our fingertips.
They are useful only as a form of identification. DNA profiling may be used for identification purposes, but the DNA itself represents far more than a fingerprint. Indeed, it trivializes DNA data banking to call it a genetic fingerprint and in Massachusetts lawmakers have specifically rejected that term. But the amount of personal and private data contained in a DNA specimen makes its seizure extraordinary in both its nature and scope. The DNA samples that are being held by state and local governments can provide insights into the most personal family relationships and the most intimate workings of the human body, including the likelihood of the occurrence of over 4,000 types of genetic conditions and diseases.
