Apparently there is still a lot to learn about Fields, the person who drove a car into a crowd on behalf of white supremacy.  Not clear whether his mother is employed or totally disabled...why they moved to Ohio if not for better work.  Anyway, I am suspicious of diagnoses...especially diagnosing minors as "schizophrenic".  He did have severe problems, it is clear.  Beating on his mom and developing early age Hitler worship often accompanies a number of types of mental illness.

Two issues here because prevention needs to be our goal.  We need to be aware of signs.  Our military often wastes our tax dollars in recruiting such as Fields who may bomb out early or late...often after committing atrocities such as at Fort Hood.    The army could be our early warning system about who needs real treatment/monitoring.

Second, some studies have indicated domestic shooters...often with terrorist motives...often fit a profile of the unemployed male, former military, living with parent(s).
