There is a confounding factor. Death penalty states have higher crime rates ad sum.

That's an interesting fact. Do you think there's a causal relationship?

The tendency is crime has dropped for time for both groups.

Yes. I think it's due to the lower percentage of young males in the population, compared to the 70s and 80s. Do you see any other factor?

I have not done diligence to the topic. just an old hand at research making common logical comments. You would have you weight each state by population and stratify on age to show better results. The general hypothesis, less young males is highly possible.

The founder of Scotland Yard once remarked that the severity of the punishment did not deter crime as much as does the certainty of getting caught.

Those going on mass murdering rampages know that they're going to get caught, hence they're not deterred by either the severity of the punishment nor the idea of getting caught.
