Who cares if the US is monitoring phone numbers. If it prevents another 911 its worth it. They are not listening to conversations and not identifying individuals. All they are doing is looking for patterns in the phone calls. Citizens are already giving the government a tremendous of information every April 15th. What's the difference. God if a policeman parks his car and takes down license plate numbers and calls them it nobody seems to care. All of a sudden the liberals are up in arms- but this is what they created when they increased the power of government by giving them more control over our lives with their stupid laws.
