The ankle bracelet is the answer
I guess Goddard forgot in all the craziness but Crasswell's lawyer's fingerprints and DNA would have been all over that ankle bracelet so instead of losing his cool and acting like a crazy man at the party he should have just laughed and called the Financial Editor at the LA Times when he realized Crasswell had tried to screw him over and then given an exclusive interview explaining what had happened over the phone (without having to show himself to the editor...I'm pretty sure people knew what this rich guy sounded like if he is a west coast version of Donald Trump).
Then once he's calmly told his story the ankle bracelet could be dusted for prints by a detective and that would be the proof needed in court to go against Crasswell instead of the dueling earthmovers. But I guess my way wouldn't be quite as interesting to watch on film.
