I dont think they can get away with that here. As soon as someone finds out where they are, there would be so much rioting around the country at mosques by every day citizens trying to protest and get to them they would never be able to do it. At least after the first one, there would be so many hate crimes and rioting against muslims in the US, we'd end up finding and killing the sleeper cells that are here without even knowing it.
I don't know if you all saw this yet - I've been busy and have read through all post.

We are all so angry and frustrated when we see this happening in SA and Iraq, where we can't do anything about it, if it happened here on our soil we would have the opportunity to act out on that frustration.
A hostage and beheading situation here would bring down angry mobs on the mooselimb community where it occurred. Mosques would burn and they would soon realize it's not a good tactic on American soil.
