passengers on board about what steps they were taking to ensure the safety and security of the flight.

I can totally see where this heading...the captain will point a finger at the cabin crew, who will say no, the captain told us that was what he was going to do...

In the end, not a damn thing will happen and everyone will just throw their hands up into the air and say "Oh well...no harm done", and this ill-mannered man will continue to annoy and disrupt future flights with his childish antics without consequence.

God help my son if he EVER grows up to behave as disrespectfully to ANYONE as this bloke did on the flight, because I would take him out of rotation so fast his head would spin.
Honestly...this man and his family should be ashamed, and Qatar Airways and Qatar International Airport just lost a lot of my respect for their lack of a response to the situation AND a lack of a timely reply to lusitano's query about the matter.
