The social definition of crime varies slightly from the legal definition. Fare dodgers, people who steal pens from work etc., might not see themselves as criminals. Equally, police do not enforce all laws to the same extent, such as swearing in a public space. Sometimes, laws are also unpopular - social change led to amendments to laws against stalking, but controversial laws such as the Dangerous Dogs Act (that banned XL Bullies) have remained in place.
