Every time I go through such a screening I get a disturbing image in my head of 19 guys in hell laughing at our goofiness in the way we confiscate breast milk and grandma's water bottle. I used to enjoy air travel. Now it feels like defeat.
It's discouraging that you are one of very few making the obvious point today. We've got people arguing about the finer points of breast milk regulations, and most seem to be oblivious to the fact that this has nothing to do with security.
Aside from securing the cockpits, and arming the pilots, real security comes from trying to keep murdering a$$h*les off of the planes (and out of the country, for that matter).
