Compiling a database of all mentally ill people to help prevent violence, as some have suggested, is a flawed notion.
In a study done by the National Institute of Mental Health (as reported in the New York Times, Dec. 18, 2012, “A Misguided Focus on Mental Illness in Gun Control Debate”), nearly 18,000 subjects were followed over a lifetime to measure prevalence of violence.
There was no difference between people with mental illness and those without accruing in 7 percent of the sample.
People with undiagnosed or untreated schizophrenia and bipolar run a 16 percent risk.
Those whose illness is kept in balance with medication pose no more risk than you or I.
