I'd hope not, but I've lost faith that people will do the rational thing instead of the politcally expedient thing.
There wasn't too much in the way of expenses there, from what I know. It's probably a lot harder to get a pickup that can make a decent explosion than it was to board the planes on 9/11. Bombstuffs are regulated and scrutinized. It's difficult to get a good sized bomb going in the US without the feds finding out about it.Take the expenses it took to pull off something like 9/11, now spread it out over the nation. A pickup ready to blow and a driver per mall. Simultaneous attacks in everyone's back yard. Thats will mess a population up.
First one: IMO they might shop a bit differently, some would do more stuff online, but that was coming anyways and the vast majority wouldn't change their behaviors for very long. Second one: too far.How would Americans react to something like this? Something that challenges their way of spending and gratification. How far would they allow security to strip away rights like the TSA is doing before shopping centers become a bain instead of a pleasure?
