Here is a quote from above URL, stating court martial found no negligence or intent in the deaths.
"Ambassador Hubbard: Let me try to answer your first question, and then perhaps
General LaPorte can answer the second one. It is quite clear that U.S. soldiers operating a tank
during a combined exercise on a public road in Korea killed those two young girls. We take
responsibility for that. The question is, does that constitute a deliberate act
of murder? No, of course it didn’t. Did it constitute a negligent act? Well, the jury in this
military judicial proceeding concluded that, no, it wasn’t a negligent act. It was a terrible
accident, a tragic accident, but not one caused by intent or by negligence."
