That's just it. People who are truly mentally ill don't go on deadly rampages. There have been people who had mentally ill issues for thousands of years that have not gone on killing rampages.
They are more full of hurt from life circumstances or if there is truly a chemical imbalance, they shrivel up into themselves and cry, verbal outbursts or go catatonic. There are those who suffer from paranoid schizophrenia, but even then, those people in the past rarely attack others with such
premeditated purpose.
Now, I would be more apt to believe that people who are on illegal substances such as bath salts, crystal meth, LSD and other substances including prescribed SSRIs that do cause hallucinations have altered minds and caused violence .
I do believe that toxic excitotoxin substances that are allowed and put into our food supply (ie: aspartame, monosodium glutamate (msg), red dye, yellow dye and other chemicals) help to create mental confusion and angst.
What are excitotoxins?
Excitotoxicity is the pathological process by which nerve cells are damaged and killed by excessive stimulation by neurotransmitters such as glutamate and similar substances. This occurs when receptors for the excitatory neurotransmitter glutamate (glutamate receptors) such as the NMDA receptor and AMPA receptor are overactivated. Excitotoxins like NMDA and kainic acid which bind to these receptors, as well as pathologically high levels of glutamate, can cause excitotoxicity by allowing high levels of calcium ions (Ca) to enter the cell. Ca influx into cells activates a number of enzymes, including phospholipases, endonucleases, and proteases such as calpain. These enzymes go on to damage cell structures such as components of the cytoskeleton, membrane, and DNA.
Eat asian foods? They put loads of MSG in it for flavor. MSG is a flavor enhancer. Accent ...found in the spice section...main ingredient is MSG.
Actually, most processed foods have MSG and aspartame in them.

There most likely are many reasons for such violence in our country today. Hate and anger being one of them. But I also think that the things we ingest in our country have a lot to do with it too.
