It’s kind of scary t see the ideas from the movie Gattaca enter the real world with Kuwait creating a DNA database for all of it’s residents. It is in response to a local terrorist incident. And there are legal consequences for those who give fake samples.
In the European Union, such a database has been declared by illegal after the European Court of Human Rights ruled in 2008 that keeping a non-criminal’s DNA sample “could not be regarded as necessary in a democratic society”.
Such a database has serious privacy and ethical considerations as to how to information could be used or abused.
