Unbelievable!  Schools have absolutely no right to traumatize children in this way.  Running drills to prepare for a shooting event might be appropriate, but it should be done from an aspect of having control of the situation.  This would let the children and their parents know that there is a plan in place to assure their safety in this or other unforeseen events.  Parents should be made aware ahead of time, also, so they can tell their child about it.  They would know best how their child might react to such a drill and prepare them or express their concerns to the school.   The person at the school who decided to hold a drill without any forewarning should be fired!  This person is very dangerous and should not be permitted to be around anyone’s children.  The progressive agenda is to instill fear of firearms so that a generation will grow up wanting the government to protect them from guns.  They will grow up willing to give up their Constitutional rights for a false sense of security.  They are playing mind games with our children.  Parents must speak up and end this fear, intimidation, and indoctrination of our children, because that is what this is.  It is unconscionable and yes, the envelope has been pushed way too far in this case.  Children must be assured that adults are in control and able to protect them from harm.
