So S/L Burke was not called as an "expert witness" !!
Does that not point to a "cover up" !!
I attended the BoI for a crewman that was killed in SA many years ago, experts were called as well as witnesses to the tragic event ! (Being only some 50yds away i was called as a witness).
Surely S/L Burke's evidence would have been crucial in a big way in this case.
