Very much agreed.
But worth saying that the French state had earlier declined to pursue corporate manslaughter charges. A collection of victim families successfully appealed this decision, and those charges have now indeed come to criminal trial (NB, such trials in France are primarily investigative, not confrontational, before a verdict).
Plus - imho - an adverse corporate manslaughter verdict may have more impact on company behavior than a "rogue individual" verdict. Air France and Airbus are using a defence of "the crew messed up", while the prosecutors are arguing that the corporate systems messed the crew up. A corporation can insure - and build in the cost of insurance - against the consequences of the former. Much more difficult to insure against the latter, so investors should (Ha! "should".....) prefer corporate re-thinks. Or maybe I'm a cock-eyed optimist......
