Only if they are criminals?
You do not need to be a criminal, you only need to be afraid that DNA will be misused in the future.
Political dissident, activists and whistle-blowers come to mind.
Misused how exactly? It is extremely trivial to collect someone’s DNA if you are trying to actively target them… but even then… what would the gov do with it wrt activists dissidents etc? maybe I need to read more sci-fi
> French diplomatic sources told Reuters that Mr Macron had been told to choose between accepting a Russian PCR test to get closer to Putin or abide by strict social distancing rules.
> "We knew very well that meant no handshake and that long table. But we could not accept that they get their hands on the president's DNA," one of the sources told Reuters.
> The source did not elaborate on how the Russian intelligence services could exploit Mr Macron's DNA.
Doesn't provide insight into why one should be concerned, but it's useful information to know that nation states are wary of each other in this regard for some reason even if we don't know what that reason is.
Or just be a little thoughtful. If I want to persecute homosexuals, I can go ta a gay bar and collect DNA. If I want to persecute crypto-Jews, whenever we bust a place where some of them have gathered to worship, we can catch the others in the area by collecting DNA.
In the general case: we can designate a place to be an enemy place, and arrest the people who we can prove have been in that place.
It seems to me like DNA is just new and techie so people are inherently thinking it is more useful and scary than it really is.
