I agree. There hasn't been a terrorist attack on US soil since 9/11, but there have been several plots that were uncovered and arrests made.
Unfortunately, I don't know how much longer our 1000 batting average is going to hold up. I fear it is only a matter of time that one will succeed, and if those opposed to renewing the Patriot Act have their way, the odds will be even higher that the bad guys will succeed.
