Most mass shootings involve angry children of divorce, who are often substance abusers themselves. When divorces are prevented by substance abuse recovery, you will see fewer angry children of divorce. Note: Adam Lanza was a very angry child of divorce. He went downhill quickly after the divorce. I suspect that his mother abused pharmaceuticals or alcohol based on her odd behavior. Adam was likely on mood-altering substances himself. This has not yet been talked about publicly. I would like to know -- for the record.
