Amen.
9-11 will not happen again because anyone who acts-up on a plane now risks being beaten to death by his fellow passengers.
That’s my single argument too. We were naive before 9/11, we didn’t understand the threat.
It would never happen today, the PASSENGERS are the real security.
I tend to have an attitude going through airport security. The machine is going to tell them my groin has something to check. They aren’t friendly, don’t consider you a customer, and never say please.
I even had one that told me it was “my job” to stack empty bins, that weren’t mine, on the exit side of the security check. I informed him I’ve been ROBBED in a TSA security line, money in my bin went missing, and that my only job was to make sure I had all my belongings. The guy just starred at me...had an obvious power trip going on.
