Pilferage of laptops is a common occurrence. The last time my daughter on way back from school in Europe packed her laptop with checked in luggage id didn't arrive. While working in the airline industry some years ago this was one of the most common occurrences reported to us. Unfortnately, as with most of the things coming out of the USA these days, the directive is half baked. That the UK chooses to copy the US instead of working through EASA is sign of things to come. Not encouranging at all.
