Are terrorists doing mass murder, really mentally ill?

Is there really a scientific connection between mentore disease and gun killings? After any mass assault on America, there is always a discussion on whether the attacker's mental health should be blamed.

A recent study showed that the news media link mental illness to enormous violence, which does not stand. Then you have Donald Trump giving this speech:

I think mental health is the problem here. This is based on preliminary reports, dealing with a very degenerate individual. ”

Yes, the attacker you're talking about had mental problems in the past, but there is still a lack of scientific evidence to support the idea that America's problem with weapons is rooted in mental health. In fact, there are data that proves completely different.

Many epidemiological studies have shown that there is very little relationship between violence toward others and mental illness. This includes people who suffer from schizophrenia, bipolar disorder, and depression. The National Institute of Mental Health made the first study on the matter in 1990. They collected data from 10,000 people in three major American cities.

The study dealt with socioeconomic status and problems with substance abuse. The last conclusion was that if we somehow manage to eliminate the risk of people with mental illness, the mass of violent crimes in the US would only drop by 4%.

Some years later another study was followed by more than a thousand psychiatric patients who had been released from medical care. The study found that patients who suffered only one series of mental illness and who had no problem abusing narcotic substances posed the same risk of committing terrorist acts as other normal people.

And according to a recent study, the Health Service Department found that only 3 to 5% of violent acts can be attributed to people with serious mental illness.

Violent crime rates increase when we mix drug addicts, but this is the same for the general population. In fact, it turns out that people who suffer from mental illness are 10 times more likely to be victims of violent crimes than the common people of the general population. There are also victims of self - inflicted violence. Nearly half of America's fatalities or murders are suicides.

Experts believe that a presumption of suicide would be a better policy than the attempt to prevent gun violence, which there is a lot of evidence and data that is supposed to focus on the connections of mental illness to mass killings that there are actually no data on.

And last of all, making the scientific connection between gun violence and everything else is a difficult thing these days. That's because there was a legislation that went through the late 1990s that doesn't allow any investigation that examines gun violence as a matter of public health.
