How would you feel about having a taser in a collar at the base of yours (and everyone's) neck? It only gets turned on by the authorities if they see a crime in progress. It's perfectly harmless otherwise, right? If you're not doing anything wrong, what's to fear? In the case of markers like this, it's pretty easy to correlate by race or other heritable factors criminal behavior. If there's no harm in it, when a crime goes down in an area it seems reasonable to go and just round up all the people with rough genetic markers matching, right? It might even make sense to keep them in groups organized by genetic markers and race, since that should speed up policework dramatically. And later, if you want to procreate with somebody, maybe you should make sure their genotype won't mark your kids for poor treatment by the authorities--after all, accidents _do_ happen, and the labwork is never 100%, so better safe than sorry. Can you see why this makes people antsy?
