I would suggest that a sound defense would be that the incident was “An Act OF God”. Same as your clause in most insurance policies, if the act or event was caused by a natural event such as lightning, rain, tornado or gust of wind, it’s not your fault.

I also agree that here in the United States we are overly Politically Correct and take ourselves wayyyy toooo seriously when things like this happen.
