Highlights

 

•

CBC/MVP policies were not associated with changes in firearm homicides in California.

•

Changes in firearm suicides were similar to changes in nonfirearm suicides.

•

The null findings in California are consistent with other recent CBC evaluations.

Abstract

Purpose

In 1991, California implemented a law that mandated a background check for all firearm purchases with limited exceptions (comprehensive background check or CBC policy) and prohibited firearm purchase and possession for persons convicted within the past 10 years of certain violent crimes classified as misdemeanors (MVP policy). We evaluated the population effect of the simultaneous implementation of CBC and MVP policies in California on firearm homicide and suicide.

Methods

Quasi-experimental ecological study using the synthetic control group methodology. We included annual firearm and nonfirearm mortality data for California and 32 control states for 1981–2000, with secondary analyses up to 2005.

Results

The simultaneous implementation of CBC and MVP policies was not associated with a net change in the firearm homicide rate over the ensuing 10 years in California. The decrease in firearm suicides in California was similar to the decrease in nonfirearm suicides in that state. Results were robust across multiple model specifications and methods.

Conclusions

CBC and MVP policies were not associated with changes in firearm suicide or homicide. Incomplete and missing records for background checks, incomplete compliance and enforcement, and narrowly constructed prohibitions may be among the reasons for these null findings.

SO! When you can't find evidence to support your point of view, you make up imaginary missing information and blame it on that!!  Why not just admit that your research proves that you are wrong???  OH!  NOOOOO!  That would NEVER do!!

Just like the CDC's MMWR of October 3, 2003, the report on reducing gun violence.  The conclusion was basically "We found no evidence that tough gun laws do anything to either reduce or increase crime or violence, but we KNOW they reduce crime.  Give us more money to keep studying this."

And the National Academy of Sciences released a report in 2004 saying the same thing "We couldn't find any evidence that anti-gun laws do what we claim the do, but we know they work, and lack of any evidence at all shouldn't be taken as meaning they don't work! Give us more money to keep fudging the numbers to make them fit our model."
