Just saw that news clip.
It is crazy that the employee did that and UA did not do anything for the passenger all this time (even with the criminal case) and all these other employees did nothing. It is like a pack of wolves bullying a small animal. This is really really sad for UA and for the character of these employees - and I think it is worse than the Dao incident.
When children are way out of line, you wonder what their parents teach them. When employees are way out of line, you wonder how the company trains them.
