With all of the table-pounding rhetoric, I think people may not realize just how little they disagree on.
I think everybody (or almost everybody) here agrees:
After this tragedy, we should make sure our fire safety equipment and procedures are correct.
After this tragedy, we should all see what it is that we can be mechazek in, each person according to their situation.
Nobody today can know for sure why this happened, or how it can be prevented in the future.
Most of the difference of opinion here is merely about how much emphasis to put on each point.
