No, we cannot have the police monitoring us for social and moral offences. For example, one cannot be punished if one refuses to smile at an acquaintance or say Thank you’. One cannot be punished if one doesn’t hold the door open for the person who is following.
These are good manners, or courtesy, and they have to be taught right from childhood, and they will change in different cultures and different circumstances. Whether a person follows them or not depends on the individual. However, if these little courtesies are followed, life will become much simpler and more pleasant for everyone.
