Also, if it was known that churches (for example) were strictly off-limits to the FBI or any kind of surveillance, why wouldn't they become havens for terrorists who want to plan attacks in peace and quiet?
Just asking.
They met elsewhere. Strip joints, hotels, restaurants, etc. The feds were monitoring many of their moves. But they failed miserably. Now they want to act like they're making adjustments to prevent any more terrorist attacks.
Churches and places of worship are sacrosanct. This country was 'discovered' because of religious persecution elsewhere. Now, it's happening here.
