My understand is that there were orignally nine counts of voluntary manslaughter together with charges of aggravated assault, reckless endangerment, dereliction of duty and obstruction of justice. I understand the obstruction of justice was dropped.
The reckless endangerment or dereliction of duty would be what I'd guess the prosecution is hoping to pull off...one or the other. The most slippery would be the "dereliction of duty".
I said on another thread that the government has only released charges without specifications for the court martial. I put the charge sheet HERE with the original specifications.
Of course that's mixing the legal version of apples and oranges but it's the best we can do right now.
