"A major source of research and development on criminal profiling today is the Investigative Support Unit, started as the "Behavioral Science Unit" in the late 1950s by two Federal Bureau of Investigation (FBI) employees, Howard Teten and Pat Mullany (this remains controversial). Now a part of the National Center for the Analysis of Violent Crime (NCAVC), which is one of the major components of the Critical Incident Response Group (CIRG), it consists of agents and professionals with training in behavioral or forensic science as well as consultants from the mental-health professions. This unit has amassed large amounts of data on the backgrounds, family characteristics, current behaviors and psychological traits of various types of criminal offenders, partly obtained from interviews with dozens of convicted criminals such as serial murderers. The Investigative Support Unit offers, in addition, specific training to professionals such as detectives, psychologists, and lawyers from all over the world."
Dear Boss I keep on hearing the police have caught me but they wont fix me just yet. I have laughed when they look so clever and talk about being on the right track. That joke about Leather Apron gave me real fits. I am down on whores and I shant quit ripping them till I do get buckled. Grand work the last job was. I gave the lady no time to squeal. How can they catch me now. I love my work and want to start again. You will soon hear of me with my funny little games. I saved some of the proper red stuff in a ginger beer bottle over the last job to write with but it went thick like glue and I cant use it. Red ink is fit enough I hope ha. ha. The next job I do I shall clip the ladys ears off and send to the police officers just for jolly wouldn’t you. Keep this letter back till I do a bit more work, then give it out straight. My knife’s so nice and sharp I want to get to work right away if I get a chance. Good luck. Yours truly Jack the Ripper
I hear people use these two terms interchangeably all the time, and people often ask me if they are the same thing. The answer is that they are not necessarily the same, if you use the terms from a psychiatric perspective.
Sociopath - someone diagnosed with Antisocial Personality Disorder. Using the criteria in the DSM-IV-TR to make a diagnosis of Antisocial Personality Disorder, an individual can be diagnosed with the disorder without endorsing the symptom of being remorseless.
Lack of remorse/conscience is the hallmark of Psychopathy.
Therefore, some individuals may be diagnosed as Antisocial Personality Disorder but they are NOT a psychopath, if they are capable of remorse.
Other criteria for the diagnosis of Antisocial Personality Disorder include:
history of a childhood Conduct Disorder
failure to conform to social norms (ie. breaking the law)
impulsivity, failure to plan
irritability or aggressiveness (often resulting in physical fights)
reckless disregard for the safety of others
consistent irresponsibility, failure to sustain employment/meet responsibilities
You must be 18 years old to be diagnosed with Antisocial Personality Disorder, and there must be a pervasive pattern of these symptoms in your life which interferes with your employment, social life or education.
