The calls came in about 4:45 p.m. about an incident at Grove and Prospect Streets in the area near the Law School.
Witnesses report hearing a loud explosion. Other witnesses have reported seeing damage to a mailroom. A floor may have also partially collapsed.
Firefighters are setting up a second perimeter around the building.
There's no word what specifically happened or whether anyone was hurt.
A spokeswoman for the FBI in New Haven told the Associated Press that members of the agency's Joint Terrorism Task Force were dispatched to the scene.
Al Qaeda doesn't differentiate in its hate for Americans. Conservative Americans are bad, in their eyes, because they are mostly Christian, love America, and do what is necessary to defend it. Leftist Americans are bad, in their eyes, because they are mostly Jewish or atheist, believe in moral relativism, and are secularists.
At any rate, we can all see the symbolic value of Yale Law as a powerful American institution (powerful for better or for worse).
Maybe Al Quiada has hired a PR firm and is trying to win over the hearts and minds of the American public on this demonstration of good will. Next, could be Berkley, SUNY law, ACLU headquarters, etc.
Of course if they really want to extend the olive branch, I believe that the IRS headquarters would be a much appreciated gesture.
