I didn't realize how many FI-ers had law degrees, and specialized in criminal defense....
To prosecute for a criminal violation, two things must exist
MENS REA - the mental state of the violator and his intention
ACTUS REAS - the actual action itself
BOTH must exist for a prosecution (or should I say a successful prosecution)
Example
Joe, aware that his car has an exhaust leak, asks his ex-girlfriend to go with him to the store. He enters the store and tells her to stay inside, knowing she will be dead in 15 minutes. She dies and Joe gets prosecuted, because he has intent (he wanted to kill her) and he completed the action (he physically got her into the car and told her to remain in the car). Joe would not have been prosecuted if one of these elements did not exist.
Larry, is headed to the store in his beat up jalopy, his only car available, and his baby needs formula, so he has no choice. His neighbor, Cindy, would like to go the store and she joins him. Upon arrival, Cindy asks him to buy some milk and she will stay in the car and listen to her song on the radio. Unfortunately, an exhaust leak kills Cindy. Larry is not prosecuted since no intent exists nor criminal action to carry out the intent.
I am 105% sure the flight crew did not intend to kill anybody, and the "action" itself was an accident and not of an intended proactive effort to carry out criminal action.
end of story
Civil lawsuits are an entire different animal as is FAA penalties and fines
But there is nothing criminal here
