This is one of the reasons I'm categorically against any kind of DNA databases. Yes, they can be useful. But if a crime is a bit harder to solve and there is a nice & convenient match against a DNA database of for instance known offenders (or babies whose blood was sampled right after birth...) then policework will shift from 'whodunnit' to 'howdidtheydoit'. Rationalization after such a detail comes up is a path that…
'Hard cases make bad law', as the saying go. We know they won't lead to a massive crime wave of false convictions because DNA databases generally aren't abused like that, and the effects on crime are enormous: "The effects of DNA databases on the deterrence and detection of offenders" http://jenniferdoleac.com/wp-content/uploads/2015/03/DNA_Den... , Anker et al 2017.
