Clearly the pilot's fault. It can't be a TSA agent's fault...
Well I can see where El's Lawyer will take this one. The story sez the Pilot tried to Grab El's badge, THEN she(?) threw the coffee. So El's lawyer will claim self defense because the Pilot assaulted El.
You just know that is how it will go down... Which is why I say we need a culling of the lawyer heard held annually. We setup bait at a McDonalds: a large pot of Hot Coffee and we spill it on a disabled minority woman who is in the USA illegally. When the lawyers start circling the joint we trap 'em and ship 'em off to testing labs so they can be used in place of more likeable vermin like Rats and Cockroaches.
