From The Truth About Guns:

The first hearing, held on April 7, began with Amy Blasher, the Unit Chief of the FBI’s Crime Statistic Management Unit. She provided an overview of the downward trend in violent crime since 2009 and summarized the known factors that contribute to levels of crime as “population density, youth concentration, economic conditions, cultural, educational, recreational factors, family conditions, climate, effective strength of law enforcement agencies and citizens’ attitude towards crime and reporting to law enforcement.”
It comes as no surprise to the firearm and ammunition industry that gun ownership, the number of firearms owned by law-abiding Americans or the number of federally licensed firearm retailers were not among the factors listed, despite popular claims by gun control groups.
