I doubt those chosen to get bumped are truly random.   Pretty clear people who are United Mileage Plus member who are Gold, Platinum, 1K, Global Explorer or first class passengers would not get bumped, even if they were the last to book their flights.  Active duty passengers would also not get bumped.   United is not prejudiced by race, rather by $$$$, their best paying customers are protected.  As so many others pointed out all they had to do was for the ramp agent to up the incentives for passengers to volunteer leaving and there would have been takers.  Munoz, a minority rags to riches CEO needs to go.  His first tweet/email was that he supported the action of his employees but in this case a minor situation has blown up into costing United hundreds of millions in revenue & net worth.  If Munoz could not see that from the start & later his PR team had to tell him to completely apologize to Dao & the public,  get the feeling Munoz runs United like Kealoha ran HPD.
