No, the claim that the government used in court was that they would use DNA as an ID tool but what actually happens is they then run yoiur DNA through a database to try and see if it is tied to any open crimes in the system which is unconstitutional. That was the issue in the Maryland case, not that DNA was used for identification purposes but rather the authorities used it to do a widespread and open search to see if the guy's DNA mathced any DNA found in other cases.
Say you get popped for something innocuous as public drunkenness; that public indebriation charge does not give the police the probable cause to make the leap to assuming that you are also possibly a suspected serial rapist so they can then do a comparison check on your DNA against DNA that had been found in any open rape cases in their systems.
This is a case of government overreach.
how is that different from how fingerprints are used. if they find a fingerprint at a crime scene, they're gonna compare it to a database of fingerprints
not to mention they specify "a suspect facing charges relating to a serious offense", so things like "public drunkenness" seem like a strawman
