And there hasn't been a hijacking since, likely attributed to change in security measures along with armed pilots and hijackers not knowing which planes have armed pilots - https://www.usatoday.com/story/news...are-after-911-security-improvements/82375474/After the horrible events of 9/11/01, one proactive step taken was to allow some commercial pilots to be armed.
Similarly, I believe arming of teachers along with other security measures will effectively decrease school shootings as shooters won't know which teachers are armed and the new study shows no shootings at schools with armed teachers.
