The time for change is now. We have an extremely large pool of Americans that can fill the need of protecting our school children. Hundreds of thousands of veterans/former/retired police officers who have been in shoot/no shoot situations overseas and domestically are qualified for the task.
The demand is high and the individuals who can protect our children/educators, our schools, and our way of life are up to the task.
Every state can give specific state training, but the Federal government has a responsibility to start, maintain, and see this policy through.
Let educators educate and let the veterans/prior law enforcement specialists who have the skills to match this task protect our children.
This would also help our economy by creating a solid job for outstanding americans.
