Besides, in the pic I posted showing where the failure occurred there's already a dozen guys there standing around. Those are feds. They're giving orders on what materials need to be disposed of and destroyed and what evidence needs to be planted. Those cops there are there to make sure no one gets close enough to see the real evidence, before it's taken away. LOL...BTW, thanks for the explanations in your other posts on the cause of collapse. Interesting stuff.
