I think the phrase is 'security theater'. I and many others believe that 'competently armed staff' would be a significant deterrent to evil doers. Keeping in mind that, mass shootings are miniscule in the statistics of murder. However, if you google images for the phrase "israeli teachers armed with rifle" you will find a picture or two of a teacher armed with a rifle on a school field trip. Such a thing would require a mental change for the type of person who goes through the very liberal programs for Education degrees. It would also require people to face the truth that almost to an individual, every person who has committed a mass shooting has been deemed mentally ill. large numbers have been prescribed various prescription medications for their mental illness(es), and several have committed crimes in their acquisition of their tool of murder which goes to show that many gun control laws are useless when it comes to both enforcement and prevention.

Ultimately, a sufficiently creative evil person will succeed in their act of destruction should we be unprepaired, but we should not live huddled in caves out of fear, but walk courageously in the day and night about our business. If they attack, we defend with a good offense. A suicidal attacker ultimately is just another person who chooses not to produce but destroy. Seeking greatness through their destruction, we should deny them their success with our own acts producing brave children. My brother in-law is a national guardsman and a police officer. He was a boy when he ran for his life from Dean Mellberg, the man who shot the pregnant woman fleeing next to him [see http://en.wikipedia.org/wiki/Fairchild_A.... This was a formative event in my brother in-law's life obviously and has driven him to have the courage to stand and fight. The shooting occurred on an US Airforce base with fences, etc.

Hiding in a cave won't save us, fighting back will.

How dare the intruders not sign in at the front desk before they start their murderous rampage! It's so rude!

The newest elementary school in my county, had fenced gates surrounding the outdoor play areas. It wasn't long before someone insisted that the locked gates have panic (push) bar exit devices, unlocked, for safety.

Then, someone realized that a bad person could reach between the bars of the gate, and push the panic bar and release the gate. So...the panic devices were equipped with an alarm that would sound if the panic bar was pushed.

Now, the kids have fun hitting the panic bars with whatever ball they are playing with, to see if they can set the alarm off. One teacher told me they spend all of their recess time trying to stop this....
