Airport security is ineffectual

TSA inspection

A new study finds no evidence that x-raying luggage, making passengers take off shoes, or confiscating small items helps prevent attacks or incidents.

The goal isn’t to confiscate prohibited items. The goal is to prevent terrorism on airplanes. When the TSA confiscates millions of lighters from innocent people, that’s a security failure. The TSA is reacting to non-threats. The TSA is reacting to false alarms. Now you can argue that this level of failures is necessary to make people safer, but it’s certainly not evidence that people are safer.
