I foresee a new test requirement prior to approval to purchase a gun. And What do we do with someone if they test with a genetic proclivity? Force them to be medicated or have constant psychiatric oversight?
Just think of the privacy concerns. Will the government have the right to test you even against your will.....or will government have the right to your test results. Think about your own privacy after age 18 if you are tested and they say you have the gene - what will your life become? What if the test is wrong? What if you are in the percentage the test misses? This is not a good thing.
That was my first thought when I heard about this test a few days ago..
