I really wonder about the implementation of electronic data searches. Your average TSA-type person would seem to struggle with finding the 'any' key, never mind doing a deep search on a non-Windows computer. What are they going to do--a windows search for 'Secret Location of WMDs'? What really thrills me is some government stooge going through all my chat transcripts, emails, business, financial, and medical documents on my laptop with reckless abandon. There are files on my computer that I do not want run or modified.
Of course, anyone who is trying to hide something will try to bury it with false file names and extensions. After all, on my computer, 'Great Aunt Margot's Corn Chowder Recipe.docx' is really the lost 18.5 minutes of the Watergate tapes.
Then again, the best strategy might be to hide things in plain sight--after all when opening up a file called 'WINDOWS' you expect to see someone getting boned.
