Deputies will be at all St. Johns County schools, not just middle and high schools.

"Unfortunately, it's the world we live in," Forson said. "It's nothing's foolproof, but you certainly want to do everything you can to provide safety and security for our schools."

For George, it's making a difference.

"But every time I drive up and see the police car out there, I get scared like, 'What's going on inside?'" she said. "But it's a little comforting to see them there."

That stepped up deputy presence started Friday, along with a fresh look at safety procedures. The superintendent met with all district principals, and Monday, those principals reviewed their schools' individual safety plan to see what is working and what needs to be improved.

Overall, the district says its safety measures are strong, but it never wants to become complacent.

"Over time as things go well, and they are going very well, you get a little relaxed about it, so it was a reminder to all of us to make sure we do all the things we need to do," Forson said.

Even though there are no major changes to the the safety policy right now, the district says thats not to say there won't be any. Officials say it takes time to evaluate the plans, and each school is different, so they may have different needs.

The same is true in Nassau County. Officials there say they are using these events to determine what, if anything, needs to be changed.
