  That is a general problem with DNA tests, regardless of how samples are collected or potential perpetrators are identified. And it seems like the solution is known and accepted by the courts now, at least in Taiwan: "don't rely on just 17 markers when performing DNA matching tests"

    It’s not, however, a problem that can affect you if your DNA isn’t in any database in the first place.

      The man in the linked story did not have his DNA in any database that the police used - they got his name volunteered from the people present at the crime scene. So yes it is a problem that can affect you if your DNA isn't in any database.
