I agree that I would prefer being asked before someone thumbed through my books, but I don't think that it was a big deal or something to report.
And - just to add to the joy - I was once double-checked through security because I was too pleasant. You read that right - I was having my usual good day (I'm a pretty happy person, even when I'm not - does that make sense?), so I was humming happily to myself and all ready to go through security: shoes off, laptop case open, jacket over my arm, watch and cell phone tucked away, big smile and a pleasant good morning.
I went through security and was told I needed to go behind the partitions for an additional search. I asked why, and the person telling me to please step over looked a little uncomfortable. Oh well - long time before my flight and it's not like I haven't been "randomly chosen" before.
Important Security Person walks over and greets me. So - I said a happy "good morning" and asked if I could please be told why I was waved over, as nothing beeped on me and I know that I don't have anything in my carry-on that's on the no-carry list. ISP looks at me and says "Man, you ARE polite!"
"Yeah - so I am. What of it?" ISP explained that the folks were learning about behavioral profiling and that certain behaviors that could be considered out of the ordinary should be watched more closely. Apparently a pleasant, happy, polite, reasonable traveler is out of the ordinary for a 5:30am flight. So I was waved over for being too conspicuously not rude. He apologized and sent me on my way to Starbucks for a cup of coffee on him - for being so patient and polite.
I guess the TSA guy who sent me over was not a morning person.
So BEWARE, ehellions - we are now a TYPE TO BE WATCHED CLOSELY. I really wouldn't mind if folks did, as long as they learned something in the process.
