There have been no attacks--or at least any serious attempts at an attack--since Richard Reid. That was back in December of 2001. Personally I think that is because the FBI has been doing an exceptional job of infiltrating and then destroying the terrorist cells. It seems improbable that the terrorists have given up, so I guess the Patriot Act is working.

Banning knives has done absolutely nothing to enhance security. Banning butane lighters will do the same.

Pure political window dressing.
