This is anecdotal but it gets me thinking. Sometimes in the late 90s I stopped putting locks on my luggage. Locks were once or twice removed previously - and once the customs put a note saying they had done it. I was travelling to Europe, the east of Africa and various Caribbean countries. Nothing was stolen - but the key thing was me not storing anything too expensive in there. Generally all my expensive objects are delicate and will be transferred in my hand luggage.<p>Perhaps it&#x27;s safety in numbers. Perhaps it&#x27;s a kind of camouflage and not signalling anything of worth. Perhaps it&#x27;s because the level of risk of theft is incredibly low.
