This assumes that the sample of murders over the population is uniformly distributed. But I think it's very obvious this is not the case! Would you please read up on the kinds and degrees of relationships between perpetrator and victim in the statistics? You will find that the vast majority of cases involve two people who already have a prior relationship, and typically a close relationship either in a social or business sense. Random murders happen so rarely, you can be confident in the assumption that your family is safe unless you get involved with some sketchy people. But then, it's your responsibility to avoid those people, not the city's job to do that work for you.
