The Method
What is to be done when nothing is known yet? How is one to proceed? The very beginning of all scientific activity is rarely treated in undergraduate or graduate studies. The method for systematic observation has been developed exactely for this purpose, the. It consists in the application of five easily memorized formulas. They help the investigator and the researcher be more proficient observers and to make sure that no details have been left out when it comes to abduct hypotheses. The five formulas determine which steps are to be taken at first. They are listed as follows:

I.  Compare the object of observation to a model and/or to similar cases.

II.  Separate formal aspects from the contents and analyze each of them.

III.  Structure the object into functional elements, and explore each of them separately.

IV.  Explore inconsistencies, contradictions, mistakes, or astonishing coincidences within the context of the established structure.

V.  Look for the absence of signs (with models and after structuring the object).

Testing the Plausibility of Hypotheses
Then, after going through the process of systematically registering every import detail, we are able to draw first hypotheses (the abduction process according to Peirce). These hypotheses should consequently be checked for plausibility in listing systematically each sign of evidence for and each against them, in order to get a clear picture of the case.

Walder, H. & Hansjakob, Th. (2006): Kriminalistisches Denken
Textbook of criminalistics, 7th Ed.

This classic of German criminalistics was founded by the former Professor of Law and Federal Prosecutor of Switzerland, the late Hans Walder, JD. It is now in the hands of the Prosecutor and Chief of the District Juges' Office Thomas Hansjakob, JD and MSC in Economics. He has updated and substantially enlarged the body of knowledge (among others by the method of systematic observation, p.31-37). How to solve a case, that lets to believe a crime could have been committed? This book offers a comprehensive answer.

Assessment of threats and dangerousness

Fields of Application
Law Enforcement - Intelligence Services - Stalking - Domestic Violence - Clinical Psychology and Psychiatry

Analyis of inappropriate Messages
Threats, hoaxes and other inappropriate communications should be treated as signs of evidence, which have to be interpreted within the given social, cultural and individual context. Specific contexts are: work conflicts, domestic violence, problems of immigrants, threats and stalking of politicians etc. The semiotic model of communication consists of the perpetrator, his message(s), the receiver, the designated victim and potential copycats. When assessing the situation, one needs to explore the personality of the perpetrator (if known) as well as the messages that he sends with standardized catalogues of criteria, as well as the victim's behavior.

Violence and victimization:
A study of violent and sex offenders unknown to the Police

Are there a substantial number of felons who remain undetected by law enforcement over long periods of time? Do offenders get involved in crime simply because of bad luck or because of mental disorders or other factors? These are just a few of the questions that criminologists often have to answer. A study of 21,347 male army recruits and 1,160 male nonrecruits for comparison purposes was conducted on the topic of violence in 1997. This provided an ideal opportunity for criminologists to examine serious offending.

every second seat was left empty between recruits.
