This is actually an interesting question. - If you find £10,000 cash in the street, do you keep it? - If you find a watch in the street, do you keep it? - If you bought a laptop from your cousin Vinny for $50 and found out it was stolen, do you keep it? In my country of residence, all of these are crimes (theft by finding / knowingly handling stolen property). Obviously, someone could choose to keep their mouth shut... but that would not change the fact of it being a crime punishable by law.
