I am frustrated by the emotional support scams, but really! He was nipped and needed five stitches. Seeking billions is just silly. He should seek medical expenses, lost wages and maybe a court order forbidding the passenger from flying anymore. I don't think the accused will ever 'admit' they scammed and neither could they be so required. That stated, if airlines and/or the government started putting these people on the do not fly list, that just might work!
