It's funny how the anti gunners are all about taking guns away and expanding restrictions on access until the root of the issue is involved - taking guns from mentally ill and unstable people comes up. Then they are quick to run to the defense of their right to ownership of guns and privacy etc... You'll gladly put restrictions on 60 million gun owners with no criminal history and no mental illnesses, but if someone suggests we instead isolate the real people doing these shootings and restrict their ability to own guns and you scream about privacy and fairness. Comical really.
Here's the abstract from a good review article on the topic of mental illness and guns: "
Gun Policy and Serious Mental Illness: Priorities for Future Research and Policy" (E.E. McGinty, D.W. Webster, & C.L, Barry, 2014).
Abstract
Policies to restrict access to firearms among persons with serious mental illness are popular, but are they supported by evidence? As this literature review demonstrates, some things are clear: most persons with serious mental illness are not violent; risk assessment tools are not reliable at predicting who will be violent; and persons with serious mental illness and a history of substance use and abuse or trauma are more likely to be violent. More research is needed to develop thoughtful gun restriction policies that do not further stigmatize mental illness, the authors said.
Objective
In response to recent mass shootings, policy makers have proposed multiple policies to prevent persons with serious mental illness from having guns. The political debate about these proposals is often uninformed by research. To address this gap, this review article summarizes the research related to gun restriction policies that focus on serious mental illness.
Methods
Gun restriction policies were identified by researching the THOMAS legislative database, state legislative databases, prior review articles, and the news media. PubMed, PsycINFO, and Web of Science databases were searched for publications between 1970 and 2013 that addressed the relationship between serious mental illness and violence, the effectiveness of gun policies focused on serious mental illness, the potential for such policies to exacerbate negative public attitudes, and the potential for gun restriction policies to deter mental health treatment seeking.
Results
Limited research suggests that federal law restricting gun possession by persons with serious mental illness may prevent gun violence from this population. Promotion of policies to prevent persons with serious mental illness from having guns does not seem to exacerbate negative public attitudes toward this group. Little is known about how restricting gun possession among persons with serious mental illness affects suicide risk or mental health treatment seeking.
Conclusions
Future studies should examine how gun restriction policies for serious mental illness affect suicide, how such policies are implemented by states, how persons with serious mental illness perceive policies that restrict their possession of guns, and how gun restriction policies influence mental health treatment seeking among persons with serious mental illness.
