There were quite a lot of videos from survivors of collapsed buildings now with testimony about blatant violations. For example stores opening in bottom floors who simply remove columned and load bearing walls to open up the store space. When the violations aren’t merely corner cutting or negligence during construction but that clear, then testimony, photos (from said store) should be pretty easy to find. The investigation obviously still needs to find who was responsible, but at least it’s just a legal investigation and not a technical one.
