Claybird,
That also means that the matter can - and should, in my humble opinion - be pursued (on different level, that of passenger liability) based on federal statutes involving disregarding commands by federal officers, declining to act upon crew instructions and disrupting interstate commerce by keeping the aircraft on the ground because of said actions.
Opening pandora's box? Not going to happen. Will never get to a trial jury. Officers involved weren't federal, just airport employees. The airline and airport authority will settle out of court. Insurance coverage will pay whatever damages are due to the Doctor plus more.
