This chapter discusses what crime is. No matter how universally its ideas and regulations are accepted, it is important to understand and not lose sight of the fact that crime is a social construct. Because crime is socially constructed, ideas of unacceptable and criminal behaviour alter across cultures and over time. Many suggest that what is known as the ‘harm principle’ might be the best standard by which we should decide whether an activity should be criminal. This principle holds that if conduct is not harmful to others it should not be criminal, even if others strongly dislike it. The chapter also looks at the concept of deviance and identifies: what kinds of activities are disapproved of (seen as deviant) and why; which of these are criminalised and why; what the criminal law may reveal about society and what matters to it.

21. Human Rights V: Governmental Powers of Arrest and Detention
This chapter examines government powers of arrest and detention. Section I provides a three-part analysis of police powers to restrict an individual’s physical liberty under what we might regard as ‘ordinary’ laws. The first part of the chapter considers powers of ‘arrest’; the second section addresses powers of detention that arise consequent upon arrest but before the detained person has been charged with any offence; and the third considers situations in which a person can lawfully be detained without actually being arrested. Section II shifts the focus of the chapter to what we might consider to be ‘extraordinary’ laws, by describing and analysing the extent to which the constitution permits deprivation of liberty for ‘terrorist’ offences, specifically powers of arrest and detention which existed between 1945 to 1977, and then in the post-1977 era.
