Did the owners supply defective materials or labor in the construction of the building or conspire with others to do so?

Did the local building officials do slump tests at the concrete pours ( of the structural beams in particular) and concrete compressive strength testing of cores from the dried pours. Did the local officials enforce the building codes and building safety regulations? Was the structural steel concrete reinforcement inspected properly?

Lot of unanswered questions here ... Maybe, a few Building Inspectors, Architects, Building Contractors and Materialmen should be in jail too?

This sounds like more of a political witch hunt to me to absolve liability and feed someone found easily to the angry mob.
