Re: When to call it?
Stumbled across this news story:

A quick excerpt:
It appears the stage was never inspected. Homeland Security officials said Monday no permit was needed for the structure.
"There is no permitting process," IDHS spokesperson John Erickson told the Indianapolis Star. "There is no regulation on it. We do not regulate putting up of scaffolding in a business or an entertainment setting or anything of that type."
Neither Homeland Security nor the Indiana Fire Marshal's office are required to inspect outdoor stages.
WRTV 6 in Indianapolis reports that the City of Indianapolis does require a permit for temporary structures, but their inspectors were not responsible for reviewing structures on the state-owned fairgrounds.
So it looks like a pretty major structure had no oversight or regulation whatsoever. I wonder how many similar events are going on, right now, with structures that are far sketchier, but have never been inspected or had their design scrutinised?
