why must an investigator be knowledgeable about the components of the legal process?

Question

I know the common reasons why but I need to gather some more information in this. I am having a hard time finding good information on this subject.

Answer 1

As a detective/investigator I am required to be familiar with the cases I present to the courts.

I must insure ALL the elements of an offense are met by the results of my investigation! If I take a sloppy case to court, a victim is not provided justice!

It is also imperative that I obtain all my evidence of a case legally and insure I've met all my obligations in providing a fair and impartial investigation thoroughly!

This explaination only scratches the surface of the topic....but there you go!

Best wishes.

Answer 2

They must know their practice is protected by the law. The outcome of their investigations must stand up under the scrutiny of the courts, when used as evidence, which they are paid to gather.
Their work must be done, or shown to be done within the legal boundaries of the law.

Answer 3

Because investigators most often are also called to the courts to testify as "Expert Witnesses" to the discovery and findings of their investigations of the crimes. Examples - evidence, results or conclusions at the scene of those crimes.
