Is the concept that the government is responsible for eliminating all risks from everyday life realistic?

One botched attempted bombing by the “Shoe Bomber” has resulted in millions of people taking there shoes off to go through airport security. The resulting cost in time and effort has been enormous. I Is this really necessary? The terrorists win by losing!

Life is inherently risky. Do we need a Nanny State to watch over every possible way that a terrorist can attack us? A far better way is to spend the funds on the national security and intelligence agencies (CIA and FBI, etc.) with the cooperation with international agencies, to
catch the terrorists before they strike.
