Resolution criteria:
Sufficiently strong evidence is uncovered and/or someone involved in Boeing leadership is prosecuted for the assassination of one or more whistleblowers.
Does not need to be a decision made by any group within Boeing, an individual shareholder being discovered to have hired a hitman is sufficient for this market to resolve YES.
If any deaths of whistleblowers are discovered to be foul-play and there is no prime suspect/criminal trial of a murderer with motives unconnected to Boeing - this market likely also resolves YES - perhaps after a poll to decide if Manifold agrees there is sufficient evidence to conclude Boeing was involved in the death.
"We found this hitman who murdered one of these whistleblowers, but there's no evidence to connect them to leadership in Boeing..." - yeah, Boeing probably was involved in that.
So, what does Manifold think? Is Boeing killing whistleblowers?
