While I applaud any politician who wants to pour hundreds of millions of dollars of new funding into our mental health care system (even though nobody has said exactly what amount would help), we need to take a step back from a lie that politicians constantly trot out after a mass shooting or act of extreme violence.
The lie is this: that mental illness is a part of the problem and one of the causes of mass shootings.
According to the scientific research, this is not true. If you believe in science, you cannot believe politicians who spout this nonsense. Full stop.
