Of courses there are losses that have to be dealt with, but more than that there has be a spiritual and physical infrastucture in place to handle psychopathtic personalities so they don't inflict death and injury on innocent students and others.
Primarily, an early detection system must be developed to locate these loners with violent tendencies. They, then, must be prevented from obtaining weapons of destruction. If through human error, they slip through the hands of the authorities, a powerful spiritual being must be assigned to such a person to stop him from killing children, students, teachers and other helpful people in his way.
The evil forces moving these psychotic persons to murder must be bound and the forces of good within their darkened minds must be unleased so that murders will not take place.
I'm sorry that I didn't mention anything to you when the Amish children died last year.
