It doesn't take a genius to see what has to be done to enhance the security of the nation within its own borders: 1)Close the border with Mexico and station US troops there. 2) Profile those people from those nations known to harbor/support terrorism. 3)Activate the Constitutional Militia. 4)Be alert in your own town.5)Arm the airline pilots.
We don't need to destroy the Bill of Rights in order to be safer.
