Yep. There's an old puzzle/joke about an airplane crashing on the border between two countries. The punchline is: Where were the survivors buried?
The trick there is to get past survivors quickly, & have the victim focus on the burial.
Back to the case @ hand - I want to know what kind of material tensile strength was required to hang a prison, & What was the point? It's not like anything of the sort would so much as inconvenience a building, let alone prove fatal to it.
