First of all, thank you for asking. It seems to me, from the reading that I've done, that alot of fomenting is done at the local mosques. I believe that a lot of activity is "hidden" and protected by the Constitution at the mosques. The local imams preach hate to their people and who knows what else goes on in the name of jihad? We have to find a way to get into these places, find out what they're doing, and stop it -- and send these dangerous people back to where they came from.
Spies, maybe?
That's what I suggested Beth. Learn the language.
