Some say there's no risk. Some say it's one in a billion or more.

A terrorist is not going to plan an attack based on something that will happen one in a billion times.

Do you also not use seat belts in your car because there are only 40,000 deaths a year in 500 Billion passenger miles? If you made it safely does that prove that seatbelts are useless?

Do you drink and drive because the odds of being caught each time are less than 1 in 100? If you weren't caught does that prove that no one ever gets caught for DUI?

You may want to rethink your entire approach to probability, experiment design, cause-effect, etc.
