When I first saw that clip from that airplane I wondered who was screaming and what on earth was going on. From a short clip obviously you can't tell what happened prior for the situation to escalate to the point it did, that police/airport security was called in. (Apparently once they're called to remove a passenger, they have to get them off the plane...) Wonder why they didn't do what's typically done and offer compensation? and see if someone will volunteer to take that for a later flight - before they all got on the plane and before it got totally out of control.
I was just thinking... what this reminds me of is over the years kids who maybe had a dual diagnosis (cognitive impairment and emotional disorder etc.) having a complete meltdown. Or any kid, or toddler, really, to be worn out and scream and throw themselves on the ground, etc. But this just doesn't seem typical adult behavior. It probably would be a more typical adult reaction to be upset, angry, etc.and go back in the airport and raise holy heck with somebody about being bumped, but this reaction seems out of the ordinary. Made me wonder if there was something else going on with this guy. Not that he should have been carried off the plane in that manner, it certainly should have been resolved without that happening.
