And the (hypothetical) effect on the value of a company in the (hypothetical) event they are proven to assassinate critics is . . . what exactly?

If boeing is SO important to the government that justice doesn't matter, then it's probably a fuckload easier to bribe a judge or two and make sure the court cases never get anywhere than to orchestrate not one, but two, clandestine hits.
Further, why the fuck would you do the hits now? In both cases the information was brought out YEARS ago, and already in court. It hardly matters if they're alive or dead at this point.
