Federal funded security devices and personel at every public school in the United States.

Security devices similar to airports and trained security personel at every school to protect our children. You can't get a gun on an airplane, but not hard to get one into the classroom. This should have been addressed years ago. These tragedies could have been stopped by preparing for them, it's happened before and their was no reason to believe they wouldn't happen again but nothing was done. Let's do the right thing even though it's too late for many we can prevent it from happening again.
