Tragic recent events have restarted a debate in Washington about what politicians can to do to protect school children. President Obama has called for “meaningful action” to prevent killings. I agree, we need meaningful action.

As I listened to the news reports, I realized that there is nothing that politicians can do to prevent school shootings, but that doesn’t mean that nothing can be done.

Since the Gun Control Act of 1968 following the Kennedy assassination, we have seen a parade of ineffective attempts at gun control which have done nothing to prevent violence. Criminals and terrorists do not obey laws. Lawyers and legislators know little about guns and violence.

What did stop this particular coward was armed men and women. As soon as the police arrived, he killed himself. This is common in these kinds of crimes.
