You are talking rubbish too HC, and missing the wood for the trees.
How is the assertion a falling window from height would have killed someone "unverifiable sensationalism"? Are you trying to say nobody walks under the windows in Larvotto? Whether it is 5 seconds, 5 minutes or 5 hours doesn't change the point the windows are falling out.
They talked to the building management - that is how they knew there were no plans to check other windows. Who cares if there are 750 windows or 715, nor precisely how big they are? A 12x10 window will kill someone as surely as a 12x12.
The only thing that stinks is the usual peanut gallery of dumbdonkey, PDLM and others belittling someone with no proof whatsoever.
