How interesting, that Dop should accuse the man of things that are not yet discussed. I am inclined to wait and see who-said-what, rather than 'suspect' him of behaviour that you think he displayed.
You are behaving just like the cabin and flight crew! You are making presumptions about a man with no evidence. It is true that we have heard only one side of the story, it might be an idea to wait for the second side. Because the ENTIRE problem is that too many countries are now making assumptions about what people's intentions are. They are subjecting everyone to 'security' measures that have no chance of making any difference to the security of a flight. That subject has been discussed constantly here since 9/11.
My thanks to SLF for posting and I look forward to hearing the rest of the story before making up my mind.
