In the version of this article initially published there was a discrepancy between the text and Table 3 with regard to sentences of actual perpetrators. As correctly stated in Table 3, page 93, the coefficient for perpetration is 3.4 and sentences of hands-on perpetrators thus tend to be 3.4 years longer. In accordance with this, the text on page 95, second paragraph, last sentence, should read, ‘On the other hand, the sentences of actual perpetrators tend to be increased by an extra 3,4 years’.
