LEE COUNTY, Fla.- The Lee County School District continues to look at ways to improve safety and security.

It would cost $5.5 million to change classroom doors so they all lock from the inside. It will cost the district and Sheriff's Office about $2 million each to add resource officers to each elementary school permanently. The school board will have to vote on those recommendations.

Also, a new House bill would require all schools to make glass windows bullet proof by 2015, which would cost the district $15 million, but officials say this proposal is in it's very early stages.
