A new installment of “Lessons Learned” is now out. This week I discuss the sarin gas attack that Aum Shinrikyo carried out in the Tokyo subway system on March 20, 1995. In the video, I discuss how technological advances increasingly mean that governments are no longer the only ones capable of inflicting mass destruction.  Here’s a question to consider: what steps should society take to protect itself as technology makes it easier for terrorists, messianic figures, or just embittered individuals to inflict great harm? I encourage you to weigh in with your answer in the comments section below.

I hope you enjoy the video.
