You mean murderers who have been caught. The rate of solving murders has declined a lot in the last 50 years. NPR just did a special on that, but I couldn't find the link. Does anyone know about the rate of re-offending of murderers who have not been caught? Of course, in order to find that out, you have to solve the murders and look at the behavior of the murderer before they were caught or died.
