I believe that it's a good thing to be searched at airports. I will often make little comments like "Well, the taxi driver took my bag out of the trunk" when they ask "has anybody else handled your bags". Or, I'll carry scary-looking electronics (all purchased at your friendly neighborhood Radio Shack). That's a guarantee that you will get the special treatment. You see, the more people who desire the special treatment, the fewer people they will search who don't want the special treatment. The incentives all line up, and when they do, you can't stand in their way.
