Aduana Rip-Off?

And then you get one that went the other way. While re-boarding in Mexico city, my wife's carryon was open and inspected while going through security. Even I didn't realize what she had packed and what had cleared TSA inspection back in Chicago. It was a pack of "PlayDo" that she was bringing to give to a child of one of our Mexican families here. In addition there were personal grooming products for our teenage godson here. They removed all the items and closed up the little suitcase. All these items were a no no and should not have even been allowed to have made it through security in Chicago. After a brief discussion between the Mexican security agents, it was obvious to them that these were all gifts and they reopened the suitcase, put them all back in nice a neat and sent us on her way. My wife was dumbfounded about the PlayDo until I explained to her the facts about "Plastic explosives".
