So, Jennifer and I flew to Chicago during the weekend, and for reasons that are a bit long, I didn't have my driver's license with me.
Not to worry though, I knew that for a local flight, licenses or IDs were not actually required to travel within the US.

At the checkin, I showed them a copy of my real license, which they could have looked up by number, but they have no way to do that. I also had a real copy of my old license, which had expired driving privileges, but was still a perfectly good ID.
Why expired driving licenses aren't good IDs if the picture matches, is beyond me...

Anyway, I got the SSSS (special security screening something...), and the sole security guy at SJC proceeded to inspect every single pocket of my scottevest jacket while complaining to me that had too many pockets and too much stuff (he actually missed a couple of pockets).
Then, he started working on my backpack and asked me "is it as bad as your jacket?". I told him yes, he started and then just gave up because by then he had backed up the security line for 10mn.

So, outside of the fact that going through all this when I actually had a fully legit but just expired ID, and a copy of my real ID that they should be able to look up, is pretty sad.
Where they failed is that I was going through security with Jennifer, we had a combined ticket, she didn't have the SSSS, and they didn't search anything on her even though she was with me the entire time.

On the way back, it got worse though: we showed up a bit earlier at the airport (Chicago/ORD). Since I was somewhat annoyed that the previous guy emptied all the carefully sorted pockets in my scottevest, I just gave my jacket to Jennifer, I got the SSSS again, the guy barely looked at my backpack and couldn't look at my jacket since I didn't have it with me (not that he would have bothered apparently), and I went through.
Then, it occurred to me that the only reason I got SSSS was that they had written SSSS on my printed at home boarding pass. Next time, I can just print two boarding passes, they print SSSS on one, and I show the other pristine one at security.

Seriously, this stuff is just a joke!
