This is realy an interesting subject to discuss. Do you respect your nieghbour bcs of Law, or bcs of your Ethics?
Living in the UK since the past 5 months, have noticed that there are lots of issues here related to the civilian law.
Neighbours are very carefull and sensative to each other bcs of the Law.
If you drop a piece of tissue by accident in the front of a house, he would call the police for you and you would get a fine!.
