White paper on crime 2010 Part7/Chapter2/Section3
This section describes the status of repeat offenses of the research subjects.
Serious offenders are suspected of having a tendency to have a long term risk of repeating an offense (See Fig. 7-1-3-3 in Subsection 3, Section 3, Chapter 1). In this special research they were therefore followed up for about 10 years in determining whether they then repeated offenses or not. As mentioned above, to repeat offenses refers to being sentenced to imprisonment or a heavier punishment in a final judgment by the end of 2009 for an offense (excluding negligence in driving a vehicle/negligence in the pursuit of social activities causing death or injury or violation of traffic related acts) they committed after having been released from a penal institution. In addition, in this section and Chapter 4 the same type of offense as the serious offenses the research subjects committed (homicide and injury causing death being regarded as the same type) are regarded as offenses of the same type and repeat offenses are classified into the following categories according to the type of the offenses.
[1] Repeat serious offenses of the same type: refers to repeat offenses of the same type as the serious offenses the research subjects had committed.
[2] Repeat offenses of a similar type (sexual offenses): refers to repeat offenses (excluding repeat offenses that fall under [1]) but including forcible indecency being committed by research subjects that had committed rape.
[3] Repeat serious offenses of a different type: refers to repeat offenses (excluding repeat offenses that fall under [1]) that include serious offenses that differ from the serious offenses the research subjects had committed.
[4] Other repeat offenses: refers to repeat offenses that do not fall under [1]-[3] but for which imprisonment or a heavier punishment was imposed.
