only a passenger alerted authorities that a security breech had occurred
That’s what I heard. A passenger alerted ‘someone’ that none of the passengers had been screened prior to boarding.
It does raise a familiar conundrum. Imagine what would happen if we all pointed out all of the yawning gaps in the security façade. Alas, I doubt it would result in more ‘security’ but I’d bet folding that it would result in even more inconvenience to the law-abiding.
