cured schizophrenia and bipolar disorder and depression, he says, the overall problem of gun violence would still exist.
Duke University professor
and sociologist Jeffrey Swanson, who specializes in studying the link between violence
and mental illness, told Vox that even if everyone who suffers from
bipolar disorder,
schizophrenia,
and depression in the US were
cured overnight, violent crime in the US would only fall by around 4 %.
