I am horrified when I hear people, many I have great respect for, tossing out the schizophrenic diagnosis in regard to the shooter in the recent horrible massacre in Tucsan. People who are qualified to diagnose, give this diagnosis to a very small number of our fellow humans. Most, who have this diagnosis, are not violent. As someone who has spent many years delivering healthcare in an acute psychiatric setting, I have been regularly amazed at how well people do, living productive, quality lives in spite of having what can be a debilitating diagnosis.
This person responsible for the massacre in Arizona may have this diagnosis, but I hope we will not associate his behavior with this diagnosis.
