We could benefit a lot and save lives in the process if we analyzed the demographics of the latest batch of mass shooters. Most of them fall into the age range typical for the initial onset of schizophrenia. I think an analysis would show we are overusing psychotropic drugs for behavioral problems. Many of these are very strong drugs that should not be used on neurological systems that are still going through formation. The human brain goes through dramatic changes into the early twenties and we have no idea of all the short term effects it may have on behavior and ideation.
