While I agree with you that it is up to the individual to protect himself against "normal" criminal behavior, do not dismiss the efforts of law enforcement--particularly the much-maligned FBI--in stopping terrorism. The reason there have been no further suicide attacks here is because federal law enforcement has been so successful in monitoring, infiltrating, and then arresting the cells remaining in the USA after Sept. 11, 2001. The time to combat these people is in their planning stages. Once the delusional idiot straps on his bomb there is very little a citizen, even an armed one, can do to stop him.
