I'd like more details...
Why were these people chosen? Did they happen to have militant contacts overseas, even ifthey are not militant personally? If this surveillance is a result of that, and then the surveillance was quickly dropped after these persons non-involvement was establishedhen I am broadly ok with it.
If on the other hand, this was some kind of fishing expedition to penetrate the "thinking of the American muslim community or look for bad guys where there is no evidence, or if these people are kept on the list for years, then its repressive, and I want it stopped.
