How many facts do we really need? Number of terrorist attacks attempted: 0 Number of terrorist attacks prevented: 0 Number of 'suspected terrorists' screened by TSA: More than 0, with great probability they pick out more than 0 every single day at every single airport. Trying to stop terrorist attacks (at least in the US) is akin to trying to prevent a lottery winning. The statistics just don't work.
