Searching for the 540 figure it appears to be mobile phones only, there was another 300 computers. So ~840 searches for 2 million people.

/* I guess adding mobile and computer searches is wrong though, since some sizable fraction of computer owners have a mobile and would thus have had both searched. So maybe 650-700 searches? Doesn't change the magnitude of the resulting figures much, I suppose. */
But yeah there wouldn't be many searches.
But if you're _actually_ crossing a border into a country where there's internet access, why would you risk carrying any data that you wouldn't put on a postcard across that border? If you need it, download it after you've got there.

They are clearly clutching at straws using the story about the rapist as a reason to want no judicial oversight for the ability to spy on all citizens. Why can't they get the messages from the teenagers phones, if they know they were sent?
That hardly seems like totalitarian overreach. In fact it seems quite restrained and pretty reasonable - and presumably must be intelligence led, since I rather doubt they are doing this at random...!
