I happened to catch a few minutes of one of those border/customs reality shows a couple of weeks ago. A young German couple were trying to enter the US from Canada as tourists. They had very little in the way of funds and claimed that they planned on sleeping in their van while travelling. The official at the border asked them if they planned on working. They both said "no". He asked them again but warned them that their computers and phones had been searched. Again they said "no". The official then showed them correspondence that showed they were expected at a farm were they were expected to work as wwoofers. They were denied entry. Personally I don't agree that their correspondence should have been checked in the first case but I can see that this is an example of how this type of privacy invasion might be argued for by government.
