Conceptually, pattern matching isn't wrong. It's the implementation, presentation, and gross exaggeration of efficacy that is the real problem. DNA matching is still often pseudoscience voodoo the way it is used in courts for many of the same reasons that tooling marking is. Just look at Massachusetts, where they are having to retry 10's of thousands of cases because tests were botched by an malicious technician and then passed off in courts as foolproof even when the prosecution knew them to be suspect.
