Pakistan has given the US the information that has lead to the heightened alert at places of financial importance.
Now, I am gald that they have passed on what they learned from the Al-Qaeda linked computer expert. What bothers me is that almost all of the big arrests in the war on terror have been in Pakistan. In some cases, these terrorists have been taking hospitality in the homes of influential Pakistanis. Eventually, one of two things is going to have to happen:
1) The US will get tired of the Goose-that-Laid-the-Terrorist egg method, especially if an attack occurs that can be traced back to planning in Pakistan.
2) The terrorists get wise to the fact that the Pakistani government is using them as tokens to keep the US off their backs. At that point, they will have to try to find another place that will cover their presences.
