Of course we speculate on BR...it's what we do as a species across the planet...it sounds a bit too precious to state we should not speculate; after all it is a forum..and nobody sat around the Forum in Rome waiting for the barbarians to arrive on the doorstep before evolving an RA on "Intruders at the Gates, action plan to get rid of". Of course there's blame to be laid somewhere...duff design, duff construction, duff manufacture of the components, abuse of said components before the fact and during the fact...insufficient monitoring of the scaff structure...overloading the wrong part of the structure...not realizing parts of the structure were overloaded. The report might, if we speculate (further) from the other recent findings, attach a proportion of blame to all of the above to some degree...I don't suppose "Act of God" is going to be enough. What really matters, to my mind, is what we" do about the findings. Looks like the "authorities" in Indiana twigged quite quickly after the fact...yet dare we speculate why this issue was not addressed much earlier...especially as there is a history of nasty weather? These events certainly made me a bit more aware of stuff we hang at our venue and whether it is permissible to "mission creep" as it were...no was the answer. As for folk knowing about hanging stuff overhead...that does sound unduly optimistic. I have now learnt, via BR and links, that if anyone who wants to hang stuff at our venue (very rare as it happens) does NOT ask about the SWL of whatever they want to attach to BEFORE they arrive then you need to be a tad "concerned".
