Let me try to be clearer: the visibility helps.


Imagine if you walked up with a boarding pass you printed out at home, and right onto an aircraft. No checks. You don't think a few people might be more likely to bring dangerous things with them, and be bad enough or nuts enough to do something with it? You don't think checking their carry-on--even the threat of checking their carry-on--has any deterrent effect?

If you think that's not a good point, then you're right. We disagree.
