Defining Crime
The definition of what constitutes a crime is dependent on time, culture and age. Forensic psychology uses psychological theories and ideas to explain crime.

Definition of crime
- The definition of crime has changed because of alterations in cultural norms, social norms and moral values.
- The definition of what constitutes a crime is dependent on time, culture and age.
- Crime can be difficult to define because it is dependent on the social norms of the current period of time.

Crimes becoming legal
- Certain acts that were once a crime may now be legal.
- E.g. homosexuality. Homosexuality was illegal up until 1967 in the UK.
- Now, in England, Scotland and Wales, same-sex marriages are permissible and legal.

Legal acts becoming crime
- Certain things that were not a crime are now defined as a crime.
- E.g. smoking in public places. It used to be the social norm to smoke indoors in a pub or on a plane. This is no longer acceptable because of increased awareness of the harmful effects of second-hand smoke.

Cultural relativism
- Crime is also culturally relative.
- Different cultures have different cultural norms, and so certain acts will be legal in one country but illegal in another. For example:
- Same-sex marriage is legal in the UK, but homosexuality is still illegal in some countries.
- In the UK, a person must be at least 18 years old to marry. In Saudi Arabia, there is no legal minimum.

Relevance of age
- Finally, the definition of crime will depend on the age of the offender.
- A toddler who steals an apple would not be a criminal. This is because intent and deliberation are necessary.
- The toddler may not have known they were committing a crime, so would not be accused of doing so.
- In the UK, children under the age of 10 are not considered legally responsible for any crimes they commit.
