This judge's decision really had nothing to do with proximity to Dearborn. Diggs-Taylor is a longstanding left winger. She would have made this decision anywhere.
If the administration had not appealed the ruling, I believe it would be in effect across the country, not just in that circuit. Since the appeal, her ruling is quashed until such time it is upheld by a higher court.
But I also have heard that the ruling is in effect in her jurisdiction.
I would not be surprised to find the plaintiffs (including CAIR) picked this circuit to include Dearborn so they could point to people who claim their speech was "chilled" by the wiretapping.
But, I still wonder if the judge's ruling is in effect and if it covers Dearborn. That could be an advantage to the terrorists and something the judge could have to answer for in the future.
