I think cases like that show that people aren't killing each other not because it's hard or enforcement and punishment prevents them. They don't do it mostly because they just don't want to. And if they want to, they want to kill people close to them which makes them easy to connect with the crime. Murderers who pick unrelated victims basically roam free. It's good that there's so few of them.
