The school shootings in Newtown, Connecticut are causing some to turn their focus on securing America's schools.  A safety expert says a crucial step may be missing from your child's school disaster plan.

FOX News Radio's Jill Nado reports in our ongoing series on national security:

Securing America.

That step: Practice, practice, practice.  Sonayia Shepherd is a security analyst at Safe Havens.  She says disaster drills are crucial in light of the shootings in Connecticut.

(Shepherd) "More planning, more practicing, we don't do that enough.  This happened in an elementary school and they're the most vulnerable population, and therefore, I think they should be planning more."

Shepherd is also calling for new rules that would let any adult inside a school building call for a lockdown if they see a threat.  Most schools now can only go into lockdown under orders from a top administrator.
