The Attempt to Explain Crime
Different approaches to crime analysis:
• Developmental: influences on the social and
intelectual development of an individual.
• Social: interactions between the individual and
the environment.
• Biological: genetic defects leading to criminal
behaviour.

Analysing Crime
• Crime Scene Analysis referring to “the careful
search for behavioural clues at the crime scene”
(Ainsworth, 2001).
• More effective to give “much more
emphasis to a careful consideration of
what offenders do, their actions, and the
salient characteristics that distinguish
one criminal’s actions from another’s,
rather than an attempt to build
explanations on inferences about
putative motives” (Canter, 2000).
