I think it’s about time to remind those on the right, once again, that not all domestic terrorists are Muslims. See Michael Yon’s Fight on the Home Front for details. I’d also like to point out to the left that if you restrict the ability to ’spy’ on terrorists in the US, you will be in more danger from these groups, as well as from Islamist terrorist groups.
P.S. This is old news - but there are a lot of details in there I never heard about (I knew about some arrests - but not much more than that.)
