For state leaders, protecting children in New Hampshire's schools is a top priority.
New Hampshire Homeland Security director Perry Plummer said New Hampshire has some of the safest schools in the country but every precaution needs to be taken so schools are ready for anything.
"I don't know of any state that's done more than we have post-Sandy Hook," Plummer said.
New Hampshire is investing $20 million to improve safety at over 300 schools.
He said he hopes that someday all schools will get the money needed to make upgrades.
