The Investigation is about a compassionate and logical process for police work, and treating the violent crime with the gravity and respect it deserves.

Though the central event of The Investigation is an act of brutal violence, the series does not show any violent acts. Violent crimes, including rape, murder, and assault, are described in detail but not filmed.

Sexual content is limited to discussions about sex, though it's spoken about graphically. Police discuss rape and sexual abuse, but it is not shown. Sex is also discussed as a motive for crime.

Moderate profanity is used throughout and includes "f--k," "s--t," "damn," etc.

The real life crime had global coverage.

Characters are seen casually smoking or drinking in social situations. No drug use is shown.
