When I first read your comment I agreed with it, but the more I think about it the less I do.
The assumptions are that the government has everyone's DNA so they should be able to match the DNA at the crime scene to the 10,000 people in the USA with that matching genetic markers. If the defence also has access to this information it should help your case as much as hurt it. The defence should be able to provide a plausible alternate suspect and as long as you're not guilty and they were it should be less difficult than today.
more like:
-They find DNA at the scene.
-Birthday paradox comes into play
-I happen to be in the same city at about the right time AND no one else with the same DNA markers and similar or worse alibi is in the same city AND no other convincing evidence pointing away from me OR I live in Texas
-lazy defence
-I'm fucked.
