We are All Criminal Profilers of Sorts

by Pat Brown

There is a lot of misunderstanding about what a profiler is and isn't, even within the profiling community. Hollywood hasn't helped much, with shows like Profiler!, CSI and Criminal Minds. The shows may be entertaining, but they distort the profession and process of profiling, turning criminal profilers into glamorous detectives who are a cross between psychics and Freudian psychologists. The methods used to catch the killer are exciting and usually contain some incredibly clever piece of forensic evidence.

In reality, life for criminal profilers and the cases we work rarely involve dangerous confrontations, chases, and slick labs. We sit in our offices or, if we go to a police department to work, we are put into an interrogation rooms consisting of a table and a couple of chairs. We don't even get nice windows to look out.

If I am on location, I usually stay one week, arrive at eight or nine each morning and leave at five or six in the evening. I come out of my box for bathroom breaks and lunch. I go out to the crime scenes to observe the areas; sometimes I do interviews; occasionally I will do some kind of experiment.

On my last case, I drove my rental car at excessive speed from the crime scene to a convenience store on a curvy country road, timing how long it took me. I had to do the run a dozen times, waiting in the parking lot of the building where a mass murder went down, revving my engine and waiting for a moment when traffic lightened up, when the last car passing left my view and the next car was a good gap behind. Then just before that car reached me, I floored it, sped onto the road and hauled ass toward the convenience store. If someone pulled out in front of me and slowed me down too much, the experiment failed, and I had to do it again. Finally, I got the three fastest times I could manage and drove back to the station.

I was relieved when the detective told me there were no speed cameras on the road, so I wasn't going to have to beg him to "take care of " a thousand dollars worth of fines on behalf of my investigative work. I learned from my experiment that one of my suspects could be cleared; he couldn't have driven from Point A to Point B from the time the crime went down to the time his vehicle passed the camera at the convenience store.

When the week ends, I return to home base and spend hours in my office reviewing the information and analyzing the evidence until I am satisfied. Sometimes I role-play to act out part of the crime so I can see if it could really happen that way. Sometimes I consult with experts to get a more seasoned explanation of forensics or culture or some technical issue I am not that familiar with. When I have a profile that is accurate and clearly explains my determinations and investigative findings, then I am done -- unless some new evidence or information comes to light that changes my conclusions.

There are two methods of profiling: inductive and deductive. The inductive method, which became an FBI methodology, relies on statistical research to determine the likelihood of a certain type of offender or a certain trait to be linked to a crime. The old adage that all serial killers are Caucasian came from this kind of profiling. Research, which included interviews of incarcerated serial killers, concluded that most of these kinds of criminals were white; therefore a crime committed by a serial killer pointed to a white offender. The DC Sniper case caught a lot of inductive profilers off guard. They'd profiled the offenders as white, but they turned out to be African-American. FBI profiles tend to be lists of offender traits developed more from generalizations about percentages of similar crimes rather than a thorough analysis of the individual crime.

Deductive profilers analyze the forensic evidence and the behavioral evidence at the scene and draw conclusions specific to the particular crime. Each element of the profile must be supported by that particular crime and not be drawn from general theories. Of course, deductive profilers have studied the research and understand how this knowledge can apply to the case, but they still have to keep in mind not every case will fit, and there will be anomalies. They must depend on the evidence to prove the point.

The murder of Sandra Cantu was one of these cases where inductive profiling would lead to the conclusion that a man committed this sex crime. However, Sandra's killer was a female, a church woman. The evidence actually didn't prove whether the killer was male or female; there was penetration but no semen, so all one could say, deductively, was that someone sexually assaulted the child with a solid object of some sort. On television, most of us commentating tossed out inductive theories as we had no access to the evidence. We said the police were likely looking for a male sex offender in the community. Inductive profiling alone will get you in trouble!

The processes of inductive profiling and deductive profiling are somethings all of us do in daily life. We inductively gather information about people and behaviors, and when we are confronted with a new situation and don't have time to think, we apply these generalizations and hope they are right. With more time and evidence, we are able to analyze more thoroughly, and we become deductive profilers.

Juries end up in a terrible situation because they must become profilers overnight. They don't have time to do research to increase their general knowledge of criminals and their crimes; they don't have time to study forensics, psychology, and crime scene reconstruction in order apply good deductive skills to the case; and they have lawyers from both sides, along with prosecution and defense experts, confusing them and sometimes lying to them about the evidence and its meaning.

After going through this crash course in profiling, taught by questionable practitioners, they must render a verdict and decide the course of a human life. And people wonder why I am a proponent of professional juries!
