I would gladly donate my DNA to be tested to find criminals. I signed up to 23andMe years ago just for fun, but if that data can be used to help someone who was hurt by someone genetically related to me, I am all for it. Reading the reactions here makes me feel crazy, as if their intention is to make me feel manipulated or otherwise bad. It is really interesting to me how many people are fearful of dystopian futures…
The definition of criminal can change overnight. This may not be used only to catch serial killers. Nobody is stopping the feds to use this to target political dissidents. I don't get why anyone who knows about COINTELPRO can side with the feds on issues like this. It's not like they've stopped, actually. Check out what the feds investigated about the neo-Nazi rally in Sacramento. Still want them to handle your DNA?
