  We find subtle deviations from power law behaviour in the number of crimes
committed by individuals, analysing the two main criminology databases which
track this behaviour, the Pittsburgh Young Offenders survey and the Cambridge
UK Study in Delinquent Development. The description of the data when the number
of boys committing or reporting zero crimes are excluded is different from that
when they are included. The crucial step in the criminal progress of an
individual appears to be committing the first act. Once this is done, the
number of criminal acts committed by an individual can take place on all
scales.
