Why We Have Forgotten the Worst School Attack in U.S. History

I use a set of slides of this attack during my bomb presentation, it was devastating and these old school houses made it even easier. It could still be done today, but even the most simple alarm systems schools are required to have would reduce the amount of access this bomber had. Still an insider or contractor doing repairs at a school could achieve this level of damage.

The 1927 attack is often left out of accounts of terrorism in the U.S.
