This is exactly what terrorists want: the impact of a terrorist act is, in the end, measured in money much more than in lives. They are not going to kill that many people in the end, what they want is to make people afraid and pervert all the freedom in a country. Because what they hate is our freedom, do not forget it. EDIT: BTW, being wrong (if I am) is a cause for downvotes? Grow up, you people.
The terrorists do not want to see the U.S. turn into a police state. The terrorists do not hate our freedoms. The terrorists -- and specifically I'm talking about al-Qaeda and related groups -- want "atrocities against Muslims" to end, they want support for Israel to end, they want U.S. presence in the Middle East to end.[1] Terror sects aren't B-movie villains.

What they want is to terrorize. Their success is measured in money.
Any economist will just point out that money is how most things are measured as regards human relations in a normal society.
