Comprehensive background checks and prohibitions based on violent misdemeanors had no effect on homicide rates in California.
The latest study published by the highly-credentialed researchers in these well-funded programs, “California’s comprehensive background check and misdemeanor violence prohibition policies and firearm mortality,” was designed to evaluate the effect of California’s 1991 comprehensive background check and prohibiting those convicted of violent misdemeanors policies on firearm homicide and suicide. The study period was 1981-2000, with secondary analysis up to 2005.
Using a synthetic control methodology, the researchers found that the comprehensive background check and violent misdemeanor prohibitions were not associated with changes in firearm suicide or homicide.
In conversational language, the two policies had no effect.
This can and must be used to block further attempts at “enhanced background checks” and eliminating existing background checks. They are a waste of resources in addition to being constitutionally suspect.
