Some years ago I was on a family holiday in USA. After a 45 minute flight from LA to Salt Lake City, my case went missing. It was forwarded to the hotel thirty six hours later. It was locked, as I’d left it, but inside there was a note saying it had been searched by security. The contents were all there, but in some disarray. As far as I could tell, there was nothing controversial in there that might have precipitated a search.
