I would have taken the wallet and contents to the local police station. JWs are very well aware of this saying: 'Do to others what you would want them to do to you'. I made sure when my children were small that they could grasp this principle where it came to other people's money, by telling them: 'If it doesn't belong to you then its not yours'. They were told that even if they saw just one pence lying on the ground, they were not allowed to pick it up because it did not belong to them. You can't get simpler than that. What is needed is not legislation for different scenarios, but a simple question: 'What if it were me who had lost that money?' There is also the possibility that the money belonged to a local JW!
