Don’t count on this decision standing. The Supremes will have to get involved soon as cases wend through the courts.
The program helped stop the British air bombing plot.
Now the courts decide how we prosecute a war?
The President should have the right (and constitutionally does) to prosecute a war and keep the people safe.
If this program is taken away, what should be done to keep track of terrorists?
Got any better ideas?
Why the case was brought? Read this from CBS News:
The American Civil Liberties Union filed the lawsuit on behalf of journalists, scholars and lawyers who say the program has made it difficult for them to do their jobs. They believe many of their overseas contacts are likely targets of the program, which involves secretly taping conversations between people in the United States and people in other countries.

The Judge: “Plaintiffs have prevailed, and the public interest is clear, in this matter. It is the upholding of our Constitution.”
The decision here.
