I have reviewed several sources that explain why you should not pursue a career in forensic psychology if you want to become a criminal profiler.
Most of them don't explain it very well.
But the following explanation, from the American Psychology — Law Society, explains the difference between forensic psychology and "profiling" quite well, although it's not easy to find.
Here is the path to this excellent explanation:

A Note About Criminal Profiling
Due to depictions in popular media (e.g., Silence of the Lambs, Profiler, CSI), many students express an interest in and ask questions about criminal profiling, which may be described as a criminal investigative technique based, in part, on psychological expertise and knowledge.
In reality, few law enforcement agencies employ such techniques and there is little call for such professionals. Those interested in such work would probably do better to consider a career in law enforcement than clinical-forensic psychology.
The Behavioral Sciences Unit of the FBI, does employ a few FBI agents who engage in this activity. The FBI makes a distinction between mental health and law enforcement: FBI agents are law enforcement professionals, not mental health professionals.
In order to work as a profiler, or with the FBI in any other role, it is necessary to become an FBI agent. Experience in criminal investigation is needed before an agent can even be considered for a profiling position, but only a small number of agents ever become profilers.
Since this would be a difficult goal to achieve, the FBI encourages prospective applicants who are interested in being special agents to do so because they are interested in the range of opportunities available with the FBI, not because they want to be a profiler.
Further information is available from their office in Washington, D.C. or through the FBI website.
