Vreeland, R. Canter Ed. The target in these cases was often a public building or hospital, which may have held some meaning for the individual, for example, he may feel anger against authority figures or the symbol that a hospital represents. It would certainly be useful to attempt to replicate the results using arsons drawn from different sources, for example unsolved cases or insurance records. Some arsons may be the consequence of a deviant life-style, being used as a criminal tool, for people who have little other intellectual or physical resource. Offender characteristics A second set of hypotheses for the current classification system of arson is that individuals who set fires according to a particular mode of action will be distinct from those operating in a different mode. This is a specific example of the general thesis underlying investigative psychology that the way in which a person commits crimes is a reflection of their characteristics as people Canter, Chichester: Wiley.

It is thus hypothesized that both the expressive and instrumental regions will have targets that are objects or persons.
