Time for a thought experiment.  If a group of real nasties, say members of the Iranian Revolutionary Guard, Pol Pot's henchmen, or Nazi dead-enders came to the US and started killing people just for grins, what would be our response?  In the old days, the first thing we would do would be to stop the bleeding, and make sure no more of them enter the country.  After that, put them under surveillance and start removing the most dangerous ones from US soil.  

Probably time to do the same thing with recent Muslim arrivals, which means putting the Mosques, especially the Wahhabi Mosques under surveillance.  It is where they get their training and support.  Cheers -
