How does scene prevention and service provision contribute to an incident investigation?

•Scene preservation means the police can obtain any vital evidence which can be used in court as evidence to who’s fault the accident was. Preserving the scene means the police can collect vital evidence from the scene. This contributes to an investigation because with collect vital evidence they can then find out who’s fault it actually was.

•With the special equipment the different public services have, they can minimise contamination. This means they will be able to collect vital evidence and bring the offender to justice.

•The service provision of specialist units is vital because to preserve the evidence you will have to wear and use special equipment in order to not contaminate it. This means you will be able to investigate why the incident occurred using evidence from the scene.

•By seeing what made the incident happen (providing it was an accident) then the public services can tell the councils how to improve the safety. Scene preservation helps because they will be able to find out how the incident occurred.
