Something can be done and it would make more sense. I said it on September 12th and I'll keep saying it. If we throw the foreigners out of the country who fit the terrorist profile, we greatly diminish the chances of attack and American citizens don't lose their freedom. We don't owe these people anything. We are under no obligation to allow any foreigner to come here or stay here. These people are guests of the United States and they can be told to leave at our discretion.
The government won't throw the non-citizen, middle eastern males out of America to make us more secure. The men who are most likely to cause trouble should be the focus NOT grandmas flying to visit families. The feds would rather turn our country into a police state and keep welcoming the troublemakers as before than do the sensible and effective thing to greatly reduce the threat.
