Ignacio, there are several different types. There are some like me, that are paranormal, but not many in this world. Working with police officers as a teenager, helped me develop this ability. Narcotics, where you would go deep undercover. Robbery, missing persons, internal affairs, and vice. These are just a few. One of the greatest qualities of a detective, is empathy. You will do a lot of interrogating and interviewing, so to be able to relate and calm people, is important. I work with homicide and missing persons the most. None of them, seem to not like their job.
