Think it through.
Said close relatives of that child should be on the no fly list themselves already. There’s no need to put the child on a no-fly list if his close family already is because it’s highly unlikely that he’d be traveling like that without them.
Plus, considering the size of your average six year old, just how *full of explosives* can you pack one of them?
Now, theoretically, any six year old with terrorist relative connections that is being send on a flight all by himself that looks unusually bulky, lumpy or padded, ought to raise red flags with whatever security agency is screening passengers, but that is presuming that the security agency is capable of exercising common sense and admittedly, that is a bit of a stretch.
No, I wouldn’t want to fly on a plane with terrorists, but like I pointed out, THEY - the adults- should already be on the no fly list. There’s no need to put a six year old on in that case.
I appreciate the freedom related issues, but I just think the fact that a child is that age doesn’t preclude them from being a potential security threat. They might not fly with the parents, they might fly with someone else.
Probably “no fly” would be too much, unless the person was in the family of an actual suicide bomber. Is there an “additional layer of security” list, that doesn’t go as far as “no fly”?
