9-11 23rd Anniversary Retrospective IV: 20 Questions

This column revisits one that I published in this space on the 20th Anniversary of the 9/11 Tragedy/Disaster. This column has only minor changes from the original, which are noted. Principally, it presents 20 questions concerning the events and their aftermath, which, as it happens have yet to be satisfactorily responded to. Thus, in my view, it is important to re-state and revisit them.
