I find it incredible that Richard White actually took out a machete, of all things, and continued to swing it around in the airport. It is also frightening how easily he made six homemade bombs.
While the TSA did react quickly and efficiently, it does not change the fact that White made it as far as he did with a machete. I think that there should be a baggage check earlier in the airport to check for physically dangerous things, like a machete. It still astonishes me that he actually took out a machete and cut someone.
