Now the nature of the injuries inflicted on the passenger are coming to light (two teeth knocked out, broken nose, serious concussion) I cannot believe the US criminal (not civil) legal system has achieved nothing. Apparently the perpetrator is just on "administrative leave". Whyever have they not been arrested for a serious assault and put into custody ?
The injuries are also not particularly consistent with the grab and pull from seat that we saw. To me, they sound more like someone who has been taken round the corner into the jetway and then been given a good "seeing to" by a group of giggling thugs.
