You are off base on this one. They took some, but not all of his batteries from his carry on and put them in a bin, and apparently put other things in the bin with the batteries. He could not see everything they took, and they only discussed the batteries with him. As mentioned, they were already late for a flight (due to a last minute cancellation of their original flight) so were in a hurry and the security screeners knew it. What was possible was that some items taken out of his carry on were separated from the rest and just not replaced. However, when they called, and had family check at the TSA check in (some of the family was leaving just a couple hours later)- the items were not there, and no one knew anything about them. So if they were taken out "by mistake"- where did they end up?Never seen anything like that in all of the many countries my wife and I have visited. If on a dive trip, I have several thousand dollars worth of camera equip in my back pack that gets searched 100% of the time I bring it on-board. I've never been asked to be separated from my bag for the search, ever. Sounds to me like whomever is trying to sell this story to someone, did something stupid and rather than admit it, feels it's easier to blame some Mexican TSA's. Maybe I'm off base, but it doesn't add up.
This is not an indictment of COz. Just cautionary. ... I'd go back.
