Buckle was a chess player and good at recognising the connections many of us seem to struggle with. A bit like the pieces moved by a chess player searching for an opponents weakness, people are nudged by society in one way or the other by the opportunities available to them. Many opportunities are open to all, some are not. Not every body is honest and law abiding. Sometimes people take advantage of an opportunity that they are not entitled to, this is when a crime is committed. It is society that is responsible for the pieces and prepares the rules that define the criminal act. Criminals then do the wrong thing and commit the crime.
