It's funny how different people have different approaches towards dealing with such a potential scenario. For instance, to some people, preventing others from accessing this information is a mechanism to prevent such a thing from happening in future. For others, having gun rights or living in a heavily armed society (such as USA) is a better preventative mechanism. FYI in N Korea dissidents 'genes' are removed from the society, but it's usually done by taking out all the family members of a person committing crime. So I'd say that if govt really wanted to do something, this won't really be a defense.
