> What's to prevent terrorists from going through TSA, waiting in the scanning line when everyone is still going through, and then planting a bluetooth device into someone else's bag? I never open my carryon once I have packed it.

I make it a point to hold up the whole line until it is my turn to go through the xray. It gets fun when they mandate a pat down in lieu of the millimeter wave scanner but refuse to have someone available for it.

It’s the only way to honestly say you have kept your bags under watch. If anybody tries to send in my bags without me , I immediately speak up in a loud stern voice, “That is not your bag!”

I’m not saying this as an ad hominem and simply to throw insults, but with the hopes that it will encourage you to change your behavior.

The only thing this accomplishes is making you the kind of asshole who interferes with other people that are just trying to make their flight on time. You are not highlighting flaws in the security system. You are not taking a principled ethical stance against tyranny. You are just acting like an asshole for the sake of being an asshole and making life just a little bit worse for everyone else around you.

This is not something to brag about. This is something to be ashamed of.
