I accept pax should be forced to offload for security/behavioural reasons, but violent force just because someone has f*cked up at the gate, applied to someone picked at random for offloading? No, not on. Who made the decision as to who was to be the victim? Random selection? This guy will be paid out millions.
I've been on a flight where we had to offload, to do with hot'n high at WAN. Took so long to pick the first ten, and offload ( no arguments, everyone did as asked) , that the pilot then came on and said, as the temp had just gone up another 3 degrees in the interim, (summer morning)we had to offload another ten . Just about the whole flight stood up to volunteer :-) :-)
