Take a read and see how fear is used to manipulate the People into abdicating their responsibility for maintaining Liberty in order to gain a little FALSE temporary safety.
Liberty is NOT safe. Crazy people will always do Crazy things. Be it shooting at a school, driving drunk or "Terrorism". Safety cannot be purchased through Government, it may only be financed through the eternal vigilance of a Nation's Citizens; for once that vigilance is defaulted, safety too will be removed.
