By now, someone has probably forwarded David Ray Griffin's letter on to you. But if not, see the link at bottom.
For what it's worth, my own research supports Griffin on ALL points.
Having said this, I'm going to climb onto my high horse. I want you to know how disappointed I am in you. You have done something unworthy of yourself. You have buried your head in the sand on one of the crucial issues of our time.
Several years ago, when I first brought the evidence about 9/11 to your attention, you replied that the evidence needed to find its way into print in mainstream science or engineering journals. Later, after this happened, and I brought it to your attention, you responded by feigning ignorance. You said you were not qualified to evaluate the evidence.
Baloney. You copped out.
If a theologian like Griffin can examine the evidence (which today is much stronger) in a logical and rational manner, surely we should expect no less of the world's leading linguistic scholar.
