So what happened in the Amish school shooting? Or the Bath School bombing (35 years before the 1962 decision)? Why is it that the most atheist friendly countries have the lowest homicide rates? Or with the exception of Utah, the most religious states have some of the highest murder rates. Or, with the exception of Alaska, the most irreligious states have the lowest murder rates.
Still looking for meaningful causality. Murder rate nationally is about the same as it was in 1962.
Of course that is only if you ignore the homicides committed by the state against the citizens who didn't hold the party line. (Soviet Gulag, China, Cambodian killing fields, etc)
You can't be serious - Kalifornia does not have the lowest murder rate.
The atheist friendly Soviet Union and commie China murdered tens of millions.
Murder rate nationally is about the same as it was in 1962.

It is hard to compare 1962 with today since in 1962 the sophisticated system of rescue and trauma center care did not exist. More people died from their wounds in 1962 and more survive today. What would have been a murder in 1952 is today merely a very serious injury.
