While the Mierhofer case was a success, internal reactions within law enforcement were often hostile. To traditionalists, the shift to psychology was seen as pointless because it lacked the science necessary to hold up in court. While profiling offered new investigative insight, critics questioned whether psychological predictions could be considered reliable evidence or if they risked undermining due process protections.
The general public was largely unaware of the Behavioral Science Unit (BSU) until after the Meirhofer cases, and media such as The Silence of the Lambs generated intense public attention, making the science popular. As profiling gained media popularity, multiple perspectives further complicated the matter. Social justice advocates and some agents feared that profiling would result in racial and cultural bias. Media coverage helped popularize profiling, but also exaggerated its accuracy, contributing to both public fascination and misunderstanding of its limitations. Early critics warned that profiling could reinforce bias, leading investigators to focus on specific types of suspects while overlooking others, raising ethical concerns about fairness and objectivity.

To address these reactions and prove that profiling was a science rather than mere guesswork, agents John Douglas and Robert Ressler began their landmark study in 1976. Because the Meirhofer case proved it could work, they were empowered to do a deep dive into the science, turning intuition into a scientific database by interviewing 36 serial killers, such as Ed Kemper and Ted Bundy, to transform the intuition used in the Montana case into a standardized scientific database.
