I'm an airline pilot, so you're hitting me kind of close to home. The boxcutters did not crash the airplanes. Those terrorists would have taken the airplanes with screwdrivers, broken bottles, or any other makeshift weapons. The problem is we let terrorists in the country, and then on the airplanes. They knew the people on the airplanes were not armed. The problem was the PEOPLE, not the tools. We need to stop "blaming" inanimate objects like boxcutters, knives and GUNS, and return to dealing with the real problems. A 9 year old boy with a penknife is not really a problem, and not really a criminal.
Careful now, you're using logic and dynamic thinking there. Seriously:
