"No" Terrorist Attacks

I've seen some buzz about how Dana Perino said on Sean Hannity's show that "[the US] did not have a terrorist attack on our country during President Bush's term." The next day, she posted on twitter that she meant post 9/11. Fair enough, except for the following:

Anthrax
DC Sniper
Ohio Sniper
Virginia Tech

Any others I'm forgetting?

So she's right, if you are willing to exclude those four (and of course the 9/11 attacks themselves).

Sorry, 5≠0.
