9/11 hijackers used boxcutters. TSA was created to stop future 9/11s. They search wheelchair-bound grandmothers, steal from passengers, and light billions of dollars on fire each year – all while admitting in court that they see zero active threats to defend against.
But when passengers actually bring boxcutters to the checkpoint? Yeah, they got through and a Frontier Airlines flight had to divert after one was being used by an unruly passenger.
