Consider the businesses that close shop in observance of September 11th. What would these business owners decide to do in the event that another terrorist attack took place on a different day in the future? And then another attack, and another? What if attacks with death tolls in the mid 50s occurred bi-weekly on average. The businesses that now close for september 11th could not begin closing on the days corresponding to annual anniversaries of new attacks because the impact on revenue would be too debilitating. I think the result would be the defining of different thresholds, to identify under what circumstances it is appropriate to close. Something along the lines of “Gosh, yeah June 6th was a bloody one, but our threshold is a minimum of 3,000 deaths, and the 6th was 2,243 so we’d better stay open.” I don’t much care how businesses would cope under frequent terrorist attack circumstances, it’s just that the thought of the resulting dilemma crossed my mind. This post might inadvertently bait the FBI. Note to the FBI: how are you today?
