This simple act has embarrassed an entire industry, including countless highly-paid public officials; the very same people who determine how much resource is dedicated to soothing their bruised egos.
All it takes is one person to then point out that if security had been good enough to catch actual terrorists, the suspects would have been caught before or during the act. Then not only is a chunk of the post-9/11 security apparatus exposed for the security theater it is, but the cops look lazy and stupid too.
The point is, you cannot prevent all terrorism on home soil through police enforcement. You can choke certain points like airports by doing person-by-person inspections, but you can't do much for land-based transportation infrastructure with millions of autonomous attack vectors. Terrorism is best prevented through political actions.
The majority of people are probably indifferent to this. But for some reason those people who wouldn't mind NYPD not wasting money on this investigation are less vocal or less influential or something compared to the pro-security-state advocates whose position is "OMG could have been terrorists!" The latter may be mostly bureaucrats in power (perhaps the reason for the overriding influence of this paradigm) worried about it for job security reasons, but the motive doesn't matter.
Go talk to some ordinary people sometime and behold how easily swayed they are by cable news soundbites and shit they heard from whatever trusted idiot in their social circle they happen to take seriously for no reason at all. Be sure to have some drugs at the ready for after you're done - you'll need them.
No, it isn't just bureaucrats claiming they could have blown up the bridge. If it were, the FBI wouldn't be gearing up for a nationwide manhunt to track these people down.
It's about the symbolism, not the act. If NYC, for all its counterterrorism efforts, can't catch these pranksters, it makes the public safety officials look impotent in the face of real threats.
They largely are. It's incredibly difficult to stop crimes before they're committed, and prior to any terrorist mania it was generally considered to be outside the scope of police work. Mainly because it requires a security apparatus, and authority, that is in direct conflict with an open democratic society.
This is the nerf-ball version of challenge to government authority, so instead of Tahrir you get a few kids changing a flag, and instead of a repressive government crackdown, you get increased police investigation. But the mechanisms are the same.
States, whether they be national or local governments, don't react well to open challenges to their authority, and they use every tool at their disposal to prosecute anyone that commits a crime that openly challenges the authority of the government.
Listen folks, you can't stop terrorism. A determined attacker will just find an easier target. You can't guard everything all the time.
No, but you can put everyone under the constant threat of imprisonment for nebulous reasons, or no reason at all, and there is some glitch in human reasoning that conflates the two.
100,000s of people do that every single day. It is a bridge. That is what bridges do. They carry largely unknown people across a highly visible structure.
I think you are blowing this out of proportion. Or maybe I shouldn't use the word blowing.
I just hope the pranksters don't end up in jail.
