I think that, more generally, intelligent people don't get arrested for crimes for several reasons. First, because they are smarter, they just don't get themselves into jams where murdering someone seems like the best way to get out of the jam. Second, because they are more successful they have more to lose in terms of wealth, happiness, good living situation, so they risk more when choosing crime, so they're less likely to choose it. Only thirdly is actual proficiency in the planning and execution of the crime.
