Top 4 Misperceptions of Mass Shootings and Mental Illness

Mental illness misperceptions have run wild in the wake of the latest mass shooting in Parkland, Florida. Here are the Top 4 misperceptions of mass shootings and mental illness.

Common Misperceptions

  1. Mass shootings by people with serious mental illness represent the
    most significant relationship between gun violence and mental illness.
  2. People with serious mental illness should be considered dangerous.
  3. Gun laws focusing on people with mental illness or with a psychiatric
    diagnosis can effectively prevent mass shootings.
  4. Gun laws focusing on people with mental illness or a psychiatric diagnosis
    are reasonable, even if they add to the stigma already associated
    with mental illness.

Evidence-Based Facts

  1. Mass shootings by people with serious mental illness represent less
    than 1% of all yearly gun-related homicides. In contrast, deaths by
    suicide using firearms account for the majority of yearly gun-related
  2. The overall contribution of people with serious mental illness to violent
    crimes is only about 3%. (1) When these crimes are examined in detail,
    an even smaller percentage of them are found to involve firearms.
  3. Laws intended to reduce gun violence that focus on a population representing
    less than 3% of all gun violence will be extremely low yield,
    ineffective, and wasteful of scarce resources. Perpetrators of mass
    shootings are unlikely to have a history of involuntary psychiatric hospitalization.
    Thus, databases intended to restrict access to guns and
    established by guns laws that broadly target people with mental illness
    will not capture this group of individuals.
  4. Gun restriction laws focusing on people with mental illness perpetuate
    the myth that mental illness leads to violence, as well as the misperception
    that gun violence and mental illness are strongly linked.
  5. Stigma represents a major barrier to access and treatment of mental
    illness, which in turn increases the public health burden.

    On behalf of the “president,” republicans, and the morally bankrupt and completely despicable NRA, I apologize to those who suffer from mental illness. So sorry you are the scape goats for this pure evil agenda.

  2. Jim Smith

    The issue here is civil rights. Its just as important as the Montgomery Bus Boycott where Martin Luther King earned his chops. The proposals out there amount to harassment and discrimination against gun owners. This is oppression. It is someone putting their thumb on gun owners and saying “You are unworthy. This is bigotry.

    This is worth fighting on principal.
