What is a detailled examination?
The problem I have is not that they would check stuff but that the rules should be more defined. For example, when I travel back to the UK next time I will be buying a new laptop, smartphone, and probably a PS4 for my kid. Those are things that are too expensive to buy here. Proving they are mine should be easy enough, but are they hooking up PS4's in the airport to see if they are new or used? I doubt it, so how far can you go to prove they are yours and are not going to be sold?
