There was a bomb that was set to go off in Time Square. A Pakistan born man named Faisal Shahzad, was arrested and charged for the crimes. He had spent the last five months training how to make these bombs at a terrorist camp in Pakistan. He is against the U.S. being in Iraq and did not support George W Bush at all. It wasn't hard for authorities to track him down. He got on a plane which he wasn't suppose to be on, and he paid cash for a plane ticket.
I think that even though it's a big deal about a bomb going off so close to us, that it shouldn't suprise us too much. We have had so many threats that i'm suprised something like this hasn't happened sooner after 9/11.
