There was once a mathematician who got caught at the airport with a bomb. They took him in for questioning. When asked why he had a bomb in his suitcase he stated "the odds of there being a bomb on your airplane are less than one in ten million. So I figured what are the odds of there being two bombs on my flight?" Do you see why this is similar? When an outcome (terrorism) becomes an input to its own predictor (past terrorism failures), the logic breaks.
