How is calling me "sheeplish" helpful for this conversation?
The goal of the TSA is to create security theater, and that goal is effective at preventing terrorists from even attempting to attack airports. It's difficult to prove this, of course, because how does one measure a terror cell's internal and secretive planning?
You don't get to collect data on the targets terrorists don't attack, because they... well, they don't attack them! It's intellectually dishonest to claim 1), because of this.
As for 2), this is absolutely true, but why do you think the TSA's goal is to be functionally effective? It'd be nice, obviously, but like I said in my original comment, there is value in security theater.
The head of the FBI once said that there's simply no stopping a terrorist once he has his weapon on premises. The point of the TSA is to provide a false front line for terrorists to misidentify as the significant hurdle in executing an attack, and they do that successfully. The reality is, the world's police catch terrorists before they act, the vast majority of the time.
It'd be great if the TSA were effective, and it's via shitty management that they're not, this is unmistakable. But the mere presence of the TSA at US airports is an effective misdirection, because it provides what people call "security theater", and while most folks consider security theater useless, they're wrong. It has value.
