It doesn't seem safe to me to pour out potential 'explosive' liquids into a shared bin.

Especially a bin with tons of people standing really close to.

If you want to cause actual excitement just bring an actual bomb and throw it in the rubbish before going through security. You'd kill a lot of people, cause the US (or whichever country) to chase its tail furiously for a while, and you surely wouldn't be caught.

The fact that nobody has done this to me demonstrates how vapid these threats are. The cost in human lifespans wasted in this nonsense far exceeds the number killed in the US by terrorists, foreign or domestic. At least you can read a magazine while queuing and while walking through the machine. What a farce.

In its defense, the TSA does provide paychecks for folks who are truly otherwise unemployable, though it would be cheaper to send them all home and mail the checks to them. Oh, and it provides ripe pickings for those with access to checked luggage, as has been well attested.
