To be resolved by the consensus of American sources. I may choose to resolve to Market if there is some ambiguity and the market price seems basically reasonable and not manipulated or an artifact of poor liquidity, but if not, or if it seems pretty clear cut to me, then I'll resolve to my own best judgement of the consensus of trustworthy American sources, including both government sources and news media. 

I will probably continue to delay the closing of this market until some consensus emerges and either way will probably wait several months at the minimum unless the evidence is especially clear cut. 

I will presumptively treat evidence of being the cause of the dam failure as evidence of deliberate intent to make it fail.
