Do we really WANT to shut them down?
Is it possible its much better to have them up and running and MONITORED so whatever they are communicating can be anticipated and thwarted?
Just a thought.
Another is setting up bogus terrorist websites of our own to dispense “misinformation” to create chaos in their operations.
This will be a great idea as well but we need to have the FBI and other agencies aware of this action before hand or else we may end up in jail accused wrongly of setting up terrorist websites.
