Whatever past this man has, is irrelevant regarding what happen in this case. It will bare no view on whatever settlement he deservedly receives.
Even eyewitnesses have come out stating that the man had not done anything wrong and had not been disruptive until UA decided to have him removed by force.
My prediction UA's CEO is living on borrowed time, UA have lost over 600 million on their share prices because of this, how funny how ignorant some SkyGods are, and how little respect they have for their paying customers.
