Before 911, airports were basically wide open with the exception of early generation metal detectors. Today, there are multiple checkpoints before you even get to highly sophisticated detection systems. Additionally, there are both openly armed police as well as undercover agents covering the entire airport. With the exception of a view isolated gun incidents, mostly which happened outside of the terminals. Schools would not need to be that complicated, but it seems to be the only choice to stop cowardly murderers.
