Stuff happens. Do you want a bubble wrapped society where EVERY possible precaution is taken at EVERY event just in case something might happen? I don’t.
I don’t know where you got the impression I wanted a “bubble-wrapped” society. Nothing of the sort was inferred in my remarks. The only remarks made referencing the protective level you mention was what levels of cost and effort should be directed toward a more effective street closure relating to an event. I would refer you to my latest response posted. Doing so might clarify my position in your mind. If not I don’t know how I otherwise could.
