Silver, You must be an airline employee, perhaps even a United one. Your support for United flies in the face of logic. Did you notice how CEO Munoz changed course from initially blaming the passenger to accepting responsibility for what was 100 percent wrong by United. Funny how a financial threat and public opinion changes ones opinion. Very disingenuous indeed!  This will be remembered a long time. Offering a free RT to anywhere United flies to volunteers would have been many millions cheaper than what the airline chose to do. Munoz needs to be sacked! That will serve as a deterrent to similar actions by carriers in the future. The passenger will be richly compensated for the abuse he suffered. Deservingly so! 
Can you imagine how the Chicago security police came up with accusing the passenger with falling which caused his injuries. That will play well before a jury, no? You can be assured that this will cost United dearly in China. As it should!
