She has served in the Israeli Defense Forces and the Israel National Police, and worked for the U.S. Drug Enforcement Administration as a special consultant. From 1997 through 2001, she was a member of a research team, sponsored by the National Institute of Justice, studying police integrity in three major police departments in the United States. She is the author of "Critical Issues in Police Training" (2002) and co-author of "Enhancing Police Integrity" (2006).



Maria Haberfeld says police officers make decisions based on their awareness of potential danger.



NEW YORK (CNN) -- We teach our children to think about what others feel before they act, but as grown-ups we frequently assume we understand what others do without ever having walked in their shoes.



President Obama expressed his opinion about a police officer's interaction with Harvard Professor Henry Louis Gates. "The Cambridge police acted stupidly in arresting somebody when there was already proof that they were in their own home," the president said.



Was it stupid behavior or was it an understandable result of police procedure -- the culture, or rather sub-culture, of this profession. People depend on police in a time of trouble but are quicker than lightning to judge harshly when things go wrong. But the most important question in this case is: Did they go wrong?



One needs to understand that the interaction between a police officer and a suspect is just part of a larger context.



When a neighbor calls the police to report a burglary in progress and a police officer is dispatched to respond, a decision-making process begins for the officer.



Police work is about sub-cultural contexts, about war stories, about suspicion, about unpredictability, about danger and fear for one's life. Police officers make their decisions based not just on a given situation but also based on their prior experience, the experience of those they have worked with and the stories they have heard about incidents that happened in the past.



A call to respond to a burglary in progress generates a series of images that prepare a police officer for an encounter -- a dangerous encounter that can possibly end with a loss of life.



Not long ago one of my students, an officer in the New York Police Department, was killed trying to stop a robbery in progress. Police officers hear about these stories and unlike the members of the public who forget a story, no matter how sensational within a day or two, police officers carry these stories as their secret weapons. This is part of their armor. An officer responding to a burglary in progress arrives at a scene with a heightened sense of danger, anxious and ready to go into fighting mode.



Yes, the professor identified himself as a legitimate occupant of the premises. However, he was not arrested for trespassing. He was arrested for disorderly conduct.



Police officers arriving at the scene of a suspected burglary in progress do not put down their armor of suspicion just because somebody proved to them that they are the legitimate occupants of the dwelling.



Police encounters can become deadly when officers assume that, on the surface, everything appears to be in order. It is their sixth sense of suspicion that helps them assess the situation in a way that members of the public would not consider reasonable. It is this precise quality of suspicion that goes beyond a reasonable doubt that sets them apart from the larger public and can be understood only by the members of the force.



A person usually does not break into his own house -- it is true that it can happen, and it apparently did in this case -- but this is not a standard behavior that, once explained to the officer, should mandate an automatic approach to put down your guard.



The officers look at the scene of the event they were called to as their domain, their turf, their territory, where some order has been disturbed and they were called to restore it. A famous police scholar, Egon Bittner,
