My view is that some of us *cough* I, do think he was planning some sort of lawsuit "payday" if he was on the phone with lawyer before it got physical. It's possible that with all those cellphones out, someone got something that will show it or prove it was just an innocent call looking for his rights to stay on the plane. I don't know yet.
I say that because of what's come to light about his personality and his behavior. It does make a difference knowing he allegedly prefers a quick payday without working as allegedly evidenced of the illegal drug sales, trading illegal drugs for sex, his stint as professional poker player... maybe it shouldn't be admissible in a court case, but I think it helps to explain his character and behavior.
