Sometimes I imagine what the world would look like if the Nazis had won World War II, and this kind of thing is pretty much part of that horrible vision.
So where should the line be drawn for using DNA analysis to resolve crimes? I mean how serious should crimes be before DNA analysis should be allowed? Murder, I suppose - but why not dog poo?
Living in the German city with the highest density of dogs in the country, I find dog poo highly annoying. It completely spoils the parks, for example.
