Forensic psychologists apply psychological theory to criminal investigation to help understand psychological problems associated with criminal behaviour, and the treatment of those who have committed offences.
Crimes are acts committed in violation of the law, where the consequence of conviction by a court is punishment
Crime is socially constructed and is a reflection of the beliefs and attitudes of the society.
Definitions of crime differ across cultures:
What is considered a crime in one culture may not be judged a crime in another
e.g. in 2014 forced marriage was made illegal in the UK, yet it is still practiced in some cultures.
Definitions of crime change over time:
At different historical times, people define crime differently
E.g. a parents ‘right’ to smack a child was outlawed in 2004
E.g. homosexuality was deemed a crime in the UK until 1967, making it historically specific. Homosexuality is still illegal in some countries (culturally specific)
Problems with circumstance:
There are circumstance in which the legal system can take the situation into account
Actus reus – the person should be in control of what they are doing E.g. the offender may be considered not criminally responsible due to mental illness
Mens rea – the intention to commit the act e.g. braking to avoid hitting a pedestrian but not having enough time.
Problems with age:
It is difficult to say at what age children understand the difference between wrong and right.
Age of criminal responsibility in the UK is 10 (changed in 1963)
E.g. Case of James Bulger (2 year old) murdered by 2 10 year old boys
