They didn't send the guy out, because they didn't even know he existed. He saw the report on television and remembered that it was one of many, many sites he destroyed munitions at. Maybe the army should have cataloged each every munition dump they encountered there but such a thing would be ridiculous. The whole country was covered with munition dumps. How are they supposed to know about this particular one immediately?
If those two explosives are as potent as we have been lead
to believe there would be some sort of control records of their handling.
The fact the major can't say whether or not he handled
them or not is not helpful.
My gripe is that he should have been prepared to answer
a question he was sure to be asked. I am sure he gave
an honest answer, maybe too honest.
