It's always six of one, half a dozen of the other. I was able to get a very large bottle of sunscreen on board my flight home in 2007 in Spain, where there had recently been a thwarted ETA bombing in Logrono & while the airport & security were still on high alert. Yet, when I had to go through security again in Newark, I was told it was "too large" & therefore had to be confiscated "for my safety."
In Seattle, I very often forget to take out my plastic baggie for "separate screening." Once I got caught & got a severe talking to. Several other times, nothing is ever said. And I honestly did forget each of those times, since I specifically put that "Plastic Baggie of Safety" right on top in my carry-on so I can snag it easily.
So, no walking sticks, no "dangerous" shampoos or sunscreens unless they are 3 oz or less & secured by a zip-loc plastic baggie, but oh, what's this? lighters & matches, no problemo!
And those in charge of security wonder why we laymen & women think it's all just a damn joke.
