It can also be a means of accomplishing social change. Ignorance of the law by a person who commits an offence is not an excuse for committing the offence. Everyone should know the law.

Law is very much embedded in culture.
Law happens not only in courtrooms but as part of the larger culture - our daily activities. Becoming more aware of our common sense can also shape our understanding of life and law.
