Thanks for the info on what happened to the boy in the mall.  Hopefully he and his friends learned their lesson.  To add on to what you said about construction I don't agree that it is the laborers fault or the owners fault.  From what I've seen, at least the buildings I'm involved with - buildings are designed very well and according to International Building Codes.  The problem is the construction phase.  There should be a system for inspection at each phase of construction to ensure that buildings are built according to the approved specifications.  Mistakes happen everywhere, that is why many areas have officials who inspect each construction phase and sign off on it before the next phase can begin. 

What a strange illusion it is to suppose that beauty is goodness.
