we live in a scary world.
The World is no scarier than it ever was. Certainly the minuscule risk from terrorism normal people face in daily life is no cause for the ever increasing paranoia we are seeing.
It seems the "Keep calm and carry on" of a previous generation has been replaced with "We're scared sh**less why aren't you?"
Yes, it's a shame we have to consider threats like this, and that normal people will sometimes get caught up in situations like this
Just spare a though for how they may feel about all this. Completely innocent travellers subjected to that level of suspicion and finger pointing just because of the way they look. Perhaps they are the ones with a little more justification to feel scared.
I want the Captain to retain the right to be able to off-load whoever he likes.
Maybe, but only on grounds of flight safety, not some vague predjudice.
