PoliceOne's Gun Control Survey: 11 key lessons from officers' perspectives

 When asked what they believe is the biggest cause of gun violence in the United States, officers place most of the blame on the decline in parenting and family values. They also feel criminals are released onto parole too often and too early, while others receive inadequate sentences to begin with.
The full breakdown on this section reads:

• Decline in parenting and family values: 38 percent
• Parole, early release, and short sentencing for violent offenders: 15 percent
• Pop culture influence (violent movies, video games):14 percent
• Poor identification of mentally ill individuals: 10 percent
• Guns are too prevalent and easy to obtain: 4 percent
• Economic factors/income quality: 2 percent
• Other: 14 percent
• Unsure: 2 percent 

It would seem that officers responding to the survey believe that increased numbers of dysfunctional families and an increasingly-violent culture increases the risk that unstable individuals may resort to mass murder.
