Last week, the CDC shrugged its shoulders. Heres the press release and links to the full report.
The [CDC] Task Force review of the effects of various laws showed insufficient evidence to conclude whether firearms laws impact rates of violence.
Among the areas under task force review were: bans on specific firearms or ammunition, restrictions on firearm acquisition, waiting periods for firearm acquisition, firearm registration and licensing of firearm owners, “shall issue” concealed weapon carry laws, child access prevention laws, zero tolerance for firearms in schools, and combinations of firearm laws.
A finding of “insufficient evidence to determine effectiveness” means that, based on the current body of literature, the Task Force is unable to determine whether the intervention was effective or not. The task force agreed that additional scientific studies relating to these interventions might help to provide clearer answers.
The task force is a nonfederal panel of health-care and community-based prevention experts supported by the CDC. It directs systematic reviews of scientific research across the entire spectrum of public health issues and makes practice and research recommendations based on its findings.
